bitbake: bitbake-user-manual: Fixed porno hack for hello world example

Someone hacked the http://hambedded site or it was moved and some
links to that site in the BB manual had been hijacked to point to
an entry portal for a pornography site.  Replaced the link with an
archived version that restores the integrity of the links.

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.

+Poky
+====
+
+Poky is an integration of various components to form a complete prepackaged
+build system and development environment. It features support for building
+customised embedded device style images. There are reference demo images
+featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
+cross-architecture application development using QEMU emulation and a
+standalone toolchain and SDK with IDE integration.
+
+Additional information on the specifics of hardware that Poky supports
+is available in README.hardware. Further hardware support can easily be added
+in the form of layers which extend the systems capabilities in a modular way.
+
+As an integration layer Poky consists of several upstream projects such as 
+BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information 
+e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
+
+The Yocto Project has extensive documentation about the system including a 
+reference manual which can be found at:
+    http://yoctoproject.org/documentation
+
+OpenEmbedded-Core is a layer containing the core metadata for current versions
+of OpenEmbedded. It is distro-less (can build a functional image with
+DISTRO = "nodistro") and contains only emulated machine support.
+
+For information about OpenEmbedded, see the OpenEmbedded website:
+    http://www.openembedded.org/
+
+Where to Send Patches
+=====================
+
+As Poky is an integration repository, patches against the various components
+should be sent to their respective upstreams.
+
+bitbake:
+    bitbake-devel@lists.openembedded.org
+
+meta-yocto:
+    poky@yoctoproject.org
+
+Most everything else should be sent to the OpenEmbedded Core mailing list.  If
+in doubt, check the oe-core git repository for the content you intend to modify.
+Before sending, be sure the patches apply cleanly to the current oe-core git
+repository.
+    openembedded-core@lists.openembedded.org
+
+Note: The scripts directory should be treated with extra care as it is a mix
+      of oe-core and poky-specific files.

+                          ====================
+
+This file gives details about using Poky with the reference machines
+supported out of the box. A full list of supported reference target machines
+can be found by looking in the following directories:
+
+   meta/conf/machine/
+   meta-yocto-bsp/conf/machine/
+
+If you are in doubt about using Poky/OpenEmbedded with your hardware, consult
+the documentation for your board/device.
+
+Support for additional devices is normally added by creating BSP layers - for
+more information please see the Yocto Board Support Package (BSP) Developer's
+Guide - documentation source is in documentation/bspguide or download the PDF
+from:
+
+   http://yoctoproject.org/documentation
+
+Support for physical reference hardware has now been split out into a
+meta-yocto-bsp layer which can be removed separately from other layers if not
+needed.
+
+
+QEMU Emulation Targets
+======================
+
+To simplify development, the build system supports building images to
+work with the QEMU emulator in system emulation mode. Several architectures
+are currently supported:
+
+  * ARM (qemuarm)
+  * x86 (qemux86)
+  * x86-64 (qemux86-64)
+  * PowerPC (qemuppc)
+  * MIPS (qemumips)
+
+Use of the QEMU images is covered in the Yocto Project Reference Manual.
+The appropriate MACHINE variable value corresponding to the target is given
+in brackets.
+
+
+Hardware Reference Boards
+=========================
+
+The following boards are supported by the meta-yocto-bsp layer:
+
+  * Texas Instruments Beaglebone (beaglebone)

+straightforward with a caveat for USB devices. The following examples assume the
+target boot device is /dev/sdb, be sure to verify this and use the correct
+device as the following commands are run as root and are not reversable.
+
+USB Device:
+  1. Build a live image. This image type consists of a simple filesystem
+     without a partition table, which is suitable for USB keys, and with the
+     default setup for the genericx86 machine, this image type is built
+     automatically for any image you build. For example:
+
+     $ bitbake core-image-minimal
+
+  2. Use the "dd" utility to write the image to the raw block device. For
+     example:
+
+     # dd if=core-image-minimal-genericx86.hddimg of=/dev/sdb
+
+  If the device fails to boot with "Boot error" displayed, or apparently
+  stops just after the SYSLINUX version banner, it is likely the BIOS cannot
+  understand the physical layout of the disk (or rather it expects a
+  particular layout and cannot handle anything else). There are two possible
+  solutions to this problem:
+
+  1. Change the BIOS USB Device setting to HDD mode. The label will vary by
+     device, but the idea is to force BIOS to read the Cylinder/Head/Sector
+     geometry from the device.
+
+  2. Without such an option, the BIOS generally boots the device in USB-ZIP
+     mode. To write an image to a USB device that will be bootable in
+     USB-ZIP mode, carry out the following actions:
+
+     a. Determine the geometry of your USB device using fdisk:
+
+     # fdisk /dev/sdb
+     Command (m for help): p
+
+     Disk /dev/sdb: 4011 MB, 4011491328 bytes
+     124 heads, 62 sectors/track, 1019 cylinders, total 7834944 sectors
+     ...
+
+     Command (m for help): q
+
+     b. Configure the USB device for USB-ZIP mode:
+     
+     # mkdiskimage -4 /dev/sdb 1019 124 62
+
+     Where 1019, 124 and 62 are the cylinder, head and sectors/track counts
+     as reported by fdisk (substitute the values reported for your device).
+     When the operation has finished and the access LED (if any) on the
+     device stops flashing, remove and reinsert the device to allow the
+     kernel to detect the new partition layout.
+
+     c. Copy the contents of the image to the USB-ZIP mode device:
+
+     # mkdir /tmp/image
+     # mkdir /tmp/usbkey
+     # mount -o loop core-image-minimal-genericx86.hddimg  /tmp/image
+     # mount /dev/sdb4 /tmp/usbkey
+     # cp -rf /tmp/image/* /tmp/usbkey
+
+     d. Install the syslinux boot loader:
+
+     # syslinux /dev/sdb4
+
+     e. Unmount everything:
+
+     # umount /tmp/image
+     # umount /tmp/usbkey
+
+  Install the boot device in the target board and configure the BIOS to boot
+  from it.
+
+  For more details on the USB-ZIP scenario, see the syslinux documentation:
+  http://git.kernel.org/?p=boot/syslinux/syslinux.git;a=blob_plain;f=doc/usbkey.txt;hb=HEAD

+
+Texas Instruments Beaglebone (beaglebone)
+=========================================
+
+The Beaglebone is an ARM Cortex-A8 development board with USB, Ethernet, 2D/3D
+accelerated graphics, audio, serial, JTAG, and SD/MMC. The Black adds a faster
+CPU, more RAM, eMMC flash and a micro HDMI port. The beaglebone MACHINE is
+tested on the following platforms:
+
+  o Beaglebone Black A6
+  o Beaglebone A6 (the original "White" model)
+
+The Beaglebone Black has eMMC, while the White does not. Pressing the USER/BOOT
+button when powering on will temporarily change the boot order. But for the sake
+of simplicity, these instructions assume you have erased the eMMC on the Black,
+so its boot behavior matches that of the White and boots off of SD card. To do
+this, issue the following commands from the u-boot prompt:
+
+    # mmc dev 1
+    # mmc erase 0 512
+
+To further tailor these instructions for your board, please refer to the
+documentation at http://www.beagleboard.org/bone and http://www.beagleboard.org/black
+
+From a Linux system with access to the image files perform the following steps
+as root, replacing mmcblk0* with the SD card device on your machine (such as sdc
+if used via a usb card reader):
+
+  1. Partition and format an SD card:
+     # fdisk -lu /dev/mmcblk0
+
+     Disk /dev/mmcblk0: 3951 MB, 3951034368 bytes
+     255 heads, 63 sectors/track, 480 cylinders, total 7716864 sectors
+     Units = sectors of 1 * 512 = 512 bytes
+
+             Device Boot      Start         End      Blocks  Id System
+     /dev/mmcblk0p1   *          63      144584       72261   c Win95 FAT32 (LBA)
+     /dev/mmcblk0p2          144585      465884      160650  83 Linux
+
+     # mkfs.vfat -F 16 -n "boot" /dev/mmcblk0p1
+     # mke2fs -j -L "root" /dev/mmcblk0p2
+
+  The following assumes the SD card partitions 1 and 2 are mounted at
+  /media/boot and /media/root respectively. Removing the card and reinserting
+  it will do just that on most modern Linux desktop environments.
+
+  The files referenced below are made available after the build in
+  build/tmp/deploy/images.
+
+  2. Install the boot loaders
+     # cp MLO-beaglebone /media/boot/MLO
+     # cp u-boot-beaglebone.img /media/boot/u-boot.img
+
+  3. Install the root filesystem
+     # tar x -C /media/root -f core-image-$IMAGE_TYPE-beaglebone.tar.bz2
+
+  4. If using core-image-base or core-image-sato images, the SD card is ready
+     and rootfs already contains the kernel, modules and device tree (DTB)
+     files necessary to be booted with U-boot's default configuration, so
+     skip directly to step 8.
+     For core-image-minimal, proceed through next steps.
+
+  5. If using core-image-minimal rootfs, install the modules
+     # tar x -C /media/root -f modules-beaglebone.tgz
+
+  6. If using core-image-minimal rootfs, install the kernel uImage into /boot
+     directory of rootfs
+     # cp uImage-beaglebone.bin /media/root/boot/uImage
+
+  7. If using core-image-minimal rootfs, also install device tree (DTB) files
+     into /boot directory of rootfs
+     # cp uImage-am335x-bone.dtb /media/root/boot/am335x-bone.dtb
+     # cp uImage-am335x-boneblack.dtb /media/root/boot/am335x-boneblack.dtb
+
+  8. Unmount the SD partitions, insert the SD card into the Beaglebone, and
+     boot the Beaglebone
+
+
+Freescale MPC8315E-RDB (mpc8315e-rdb)
+=====================================
+
+The MPC8315 PowerPC reference platform (MPC8315E-RDB) is aimed at hardware and
+software development of network attached storage (NAS) and digital media server
+applications. The MPC8315E-RDB features the PowerQUICC II Pro processor, which
+includes a built-in security accelerator.
+
+(Note: you may find it easier to order MPC8315E-RDBA; this appears to be the
+same board in an enclosure with accessories. In any case it is fully
+compatible with the instructions given here.)
+
+Setup instructions
+------------------
+
+You will need the following:
+* NFS root setup on your workstation
+* TFTP server installed on your workstation
+* Straight-thru 9-conductor serial cable (DB9, M/F) connected from your 
+  PC to UART1
+* Ethernet connected to the first ethernet port on the board
+
+--- Preparation ---
+
+Note: if you have altered your board's ethernet MAC address(es) from the
+defaults, or you need to do so because you want multiple boards on the same
+network, then you will need to change the values in the dts file (patch
+linux/arch/powerpc/boot/dts/mpc8315erdb.dts within the kernel source). If
+you have left them at the factory default then you shouldn't need to do
+anything here.
+
+--- Booting from NFS root ---
+
+Load the kernel and dtb (device tree blob), and boot the system as follows:
+
+ 1. Get the kernel (uImage-mpc8315e-rdb.bin) and dtb (uImage-mpc8315e-rdb.dtb)
+    files from the tmp/deploy directory, and make them available on your TFTP
+    server.
+
+ 2. Connect the board's first serial port to your workstation and then start up
+    your favourite serial terminal so that you will be able to interact with
+    the serial console. If you don't have a favourite, picocom is suggested:
+
+  $ picocom /dev/ttyUSB0 -b 115200
+
+ 3. Power up or reset the board and press a key on the terminal when prompted
+    to get to the U-Boot command line
+
+ 4. Set up the environment in U-Boot:
+
+ => setenv ipaddr <board ip>
+ => setenv serverip <tftp server ip>
+ => setenv bootargs root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:255.255.255.0:mpc8315e:eth0:off console=ttyS0,115200
+
+ 5. Download the kernel and dtb, and boot:
+
+ => tftp 1000000 uImage-mpc8315e-rdb.bin
+ => tftp 2000000 uImage-mpc8315e-rdb.dtb
+ => bootm 1000000 - 2000000
+
+--- Booting from JFFS2 root ---
+
+ 1. First boot the board with NFS root.
+
+ 2. Erase the MTD partition which will be used as root:
+
+    $ flash_eraseall  /dev/mtd3
+
+ 3. Copy the JFFS2 image to the MTD partition:
+
+    $ flashcp core-image-minimal-mpc8315e-rdb.jffs2 /dev/mtd3
+
+ 4. Then reboot the board and set up the environment in U-Boot:
+
+    => setenv bootargs root=/dev/mtdblock3 rootfstype=jffs2 console=ttyS0,115200
+
+
+Ubiquiti Networks EdgeRouter Lite (edgerouter)
+==============================================
+
+The EdgeRouter Lite is part of the EdgeMax series. It is a MIPS64 router
+(based on the Cavium Octeon processor) with 512MB of RAM, which uses an
+internal USB pendrive for storage.
+
+Setup instructions
+------------------
+
+You will need the following:
+* NFS root setup on your workstation
+* TFTP server installed on your workstation
+* RJ45 -> serial ("rollover") cable connected from your PC to the CONSOLE
+  port on the board
+* Ethernet connected to the first ethernet port on the board
+
+--- Preparation ---
+
+Build an image (e.g. core-image-minimal) using "edgerouter" as the MACHINE.
+In the following instruction it is based on core-image-minimal. Another target
+may be similiar with it.
+
+--- Booting from NFS root ---
+
+Load the kernel, and boot the system as follows:
+
+ 1. Get the kernel (vmlinux) file from the tmp/deploy/images/edgerouter
+    directory, and make them available on your TFTP server.
+
+ 2. Connect the board's first serial port to your workstation and then start up
+    your favourite serial terminal so that you will be able to interact with
+    the serial console. If you don't have a favourite, picocom is suggested:
+
+  $ picocom /dev/ttyS0 -b 115200
+
+ 3. Power up or reset the board and press a key on the terminal when prompted
+    to get to the U-Boot command line
+
+ 4. Set up the environment in U-Boot:
+
+ => setenv ipaddr <board ip>
+ => setenv serverip <tftp server ip>
+
+ 5. Download the kernel and boot:
+
+ => tftp tftp $loadaddr vmlinux
+ => bootoctlinux $loadaddr coremask=0x3 root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:<netmask>:edgerouter:eth0:off mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)
+
+--- Booting from USB root ---
+
+To boot from the USB disk, you either need to remove it from the edgerouter
+box and populate it from another computer, or use a previously booted NFS
+image and populate from the edgerouter itself.
+
+Type 1: Mounted USB disk
+------------------------
+
+To boot from the USB disk there are two available partitions on the factory
+USB storage. The rest of this guide assumes that these partitions are left
+intact. If you change the partition scheme, you must update your boot method
+appropriately.
+
+The standard partitions are:
+
+  - 1: vfat partition containing factory kernels
+  - 2: ext3 partition for the root filesystem.
+
+You can place the kernel on either partition 1, or partition 2, but the roofs
+must go on partition 2 (due to its size).
+
+Note: If you place the kernel on the ext3 partition, you must re-create the
+      ext3 filesystem, since the factory u-boot can only handle 128 byte inodes and
+      cannot read the partition otherwise.
+
+Steps:
+
+ 1. Remove the USB disk from the edgerouter and insert it into a computer
+    that has access to your build artifacts.
+
+ 2. Copy the kernel image to the USB storage (assuming discovered as 'sdb' on
+    the development machine):
+
+    2a) if booting from vfat
+ 
+        # mount /dev/sdb1 /mnt
+        # cp tmp/deploy/images/edgerouter/vmlinux /mnt
+        # umount /mnt
+
+    2b) if booting from ext3
+
+        # mkfs.ext3 -I 128 /dev/sdb2
+        # mount /dev/sdb2 /mnt
+        # mkdir /mnt/boot
+        # cp tmp/deploy/images/edgerouter/vmlinux /mnt/boot
+        # umount /mnt
+
+ 3. Extract the rootfs to the USB storage ext3 partition
+
+        # mount /dev/sdb2 /mnt
+        # tar -xvjpf core-image-minimal-XXX.tar.bz2 -C /mnt
+        # umount /mnt
+
+ 4. Reboot the board and press a key on the terminal when prompted to get to the U-Boot
+    command line:
+
+ 5. Load the kernel and boot:
+
+    5a) vfat boot
+
+         => fatload usb 0:1 $loadaddr vmlinux
+
+    5b) ext3 boot
+
+         => ext2load usb 0:2 $loadaddr boot/vmlinux
+ 
+    => bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rw rootwait mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)
+ 
+
+Type 2: NFS
+-----------
+
+Note: If you place the kernel on the ext3 partition, you must re-create the
+      ext3 filesystem, since the factory u-boot can only handle 128 byte inodes and
+      cannot read the partition otherwise.
+
+      These boot instructions assume that you have recreated the ext3 filesystem with
+      128 byte inodes, you have an updated uboot or you are running and image capable
+      of making the filesystem on the board itself.
+
+
+ 1. Boot from NFS root
+
+ 2. Mount the USB disk partition 2 and then extract the contents of
+    tmp/deploy/core-image-XXXX.tar.bz2 into it.
+
+    Before starting, copy core-image-minimal-xxx.tar.bz2 and vmlinux into
+    rootfs path on your workstation.
+
+    and then,
+  
+      # mount /dev/sda2 /media/sda2
+      # tar -xvjpf core-image-minimal-XXX.tar.bz2 -C /media/sda2
+      # cp vmlinux /media/sda2/boot/vmlinux
+      # umount /media/sda2
+      # reboot
+
+ 3. Reboot the board and press a key on the terminal when prompted to get to the U-Boot
+    command line:
+
+    # reboot
+
+ 4. Load the kernel and boot:
+
+      => ext2load usb 0:2 $loadaddr boot/vmlinux
+      => bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rw rootwait mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)

+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is

-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free

-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE

+Takes the specified layers (or all layers in the current layer

+containing the contents of all layers, with any overlayed recipes removed
+and bbappends appended to the corresponding recipes. Note that some manual

+* where anything beyond the normal layer setup has been added to

+* overridden/appended items from bbappends will need to be tidied up
+* when the flattened layers do not have the same directory structure (the
+  flatten command should show a warning when this will cause a problem)
+
+Warning: if you flatten several layers where another layer is intended to
+be used "inbetween" them (in layer priority order) such that recipes /
+bbappends in the layers interact, and then attempt to use the new output
+layer together with that other layer, you may no longer get the same

-                    BitBake is able to build multiple images or packages
-                    using a single command where the different targets
-                    require different configurations (multiple configuration
-                    builds).
-                    Each target, in this scenario, is referred to as a
-                    "multiconfig".
-                </para>
-
-                <para>
-                    To accomplish a multiple configuration build, you must
-                    define each target's configuration separately using
-                    a parallel configuration file in the build directory.
-                    The location for these multiconfig configuration files
-                    is specific.
-                    They must reside in the current build directory in
-                    a sub-directory of <filename>conf</filename> named
-                    <filename>multiconfig</filename>.
-                    Following is an example for two separate targets:
-                    <imagedata fileref="figures/bb_multiconfig_files.png" align="center" width="4in" depth="3in" />
-                </para>
-
-                <para>
-                    The reason for this required file hierarchy
-                    is because the <filename>BBPATH</filename> variable
-                    is not constructed until the layers are parsed.
-                    Consequently, using the configuration file as a
-                    pre-configuration file is not possible unless it is
-                    located in the current working directory.
-                </para>
-
-                <para>
-                    Minimally, each configuration file must define the
-                    machine and the temporary directory BitBake uses
-                    for the build.
-                    Suggested practice dictates that you do not
-                    overlap the temporary directories used during the
-                    builds.
-                </para>
-
-                <para>
-                    Aside from separate configuration files for each
-                    target, you must also enable BitBake to perform multiple
-                    configuration builds.
-                    Enabling is accomplished by setting the
-                    <link linkend='var-bb-BBMULTICONFIG'><filename>BBMULTICONFIG</filename></link>
-                    variable in the <filename>local.conf</filename>
-                    configuration file.
-                    As an example, suppose you had configuration files
-                    for <filename>target1</filename> and
-                    <filename>target2</filename> defined in the build
-                    directory.
-                    The following statement in the
-                    <filename>local.conf</filename> file both enables
-                    BitBake to perform multiple configuration builds and
-                    specifies the two extra multiconfigs:
-                    <literallayout class='monospaced'>
-     BBMULTICONFIG = "target1 target2"
-                    </literallayout>
-                </para>
-
-                <para>
-                    Once the target configuration files are in place and
-                    BitBake has been enabled to perform multiple configuration
-                    builds, use the following command form to start the
-                    builds:
-                    <literallayout class='monospaced'>

-                    Here is an example for two extra multiconfigs:

-
-                <para>
-                    Sometimes dependencies can exist between targets
-                    (multiconfigs) in a multiple configuration build.
-                    For example, suppose that in order to build an image
-                    for a particular architecture, the root filesystem of
-                    another build for a different architecture needs to
-                    exist.
-                    In other words, the image for the first multiconfig depends
-                    on the root filesystem of the second multiconfig.
-                    This dependency is essentially that the task in the recipe
-                    that builds one multiconfig is dependent on the
-                    completion of the task in the recipe that builds
-                    another multiconfig.
-                </para>
-
-                <para>
-                    To enable dependencies in a multiple configuration
-                    build, you must declare the dependencies in the recipe
-                    using the following statement form:
-                    <literallayout class='monospaced'>
-     <replaceable>task_or_package</replaceable>[mcdepends] = "mc:<replaceable>from_multiconfig</replaceable>:<replaceable>to_multiconfig</replaceable>:<replaceable>recipe_name</replaceable>:<replaceable>task_on_which_to_depend</replaceable>"
-                    </literallayout>
-                    To better show how to use this statement, consider an
-                    example with two multiconfigs: <filename>target1</filename>
-                    and <filename>target2</filename>:
-                    <literallayout class='monospaced'>
-     <replaceable>image_task</replaceable>[mcdepends] = "mc:target1:target2:<replaceable>image2</replaceable>:<replaceable>rootfs_task</replaceable>"
-                    </literallayout>
-                    In this example, the
-                    <replaceable>from_multiconfig</replaceable> is "target1" and
-                    the <replaceable>to_multiconfig</replaceable> is "target2".
-                    The task on which the image whose recipe contains
-                    <replaceable>image_task</replaceable> depends on the
-                    completion of the <replaceable>rootfs_task</replaceable>
-                    used to build out <replaceable>image2</replaceable>, which
-                    is associated with the "target2" multiconfig.
-               </para>
-
-               <para>
-                   Once you set up this dependency, you can build the
-                   "target1" multiconfig using a BitBake command as follows:
-                   <literallayout class='monospaced'>
-     $ bitbake mc:target1:<replaceable>image1</replaceable>
-                   </literallayout>
-                   This command executes all the tasks needed to create
-                   <replaceable>image1</replaceable> for the "target1"
-                   multiconfig.
-                   Because of the dependency, BitBake also executes through
-                   the <replaceable>rootfs_task</replaceable> for the "target2"
-                   multiconfig build.
-               </para>
-
-               <para>
-                   Having a recipe depend on the root filesystem of another
-                   build might not seem that useful.
-                   Consider this change to the statement in the
-                   <replaceable>image1</replaceable> recipe:
-                   <literallayout class='monospaced'>
-     <replaceable>image_task</replaceable>[mcdepends] = "mc:target1:target2:<replaceable>image2</replaceable>:<replaceable>image_task</replaceable>"
-                   </literallayout>
-                   In this case, BitBake must create
-                   <replaceable>image2</replaceable> for the "target2"
-                   build since the "target1" build depends on it.
-               </para>
-
-               <para>
-                   Because "target1" and "target2" are enabled for multiple
-                   configuration builds and have separate configuration
-                   files, BitBake places the artifacts for each build in the
-                   respective temporary build directories.
-               </para>

-
-(Not to be confused with the code that parses the metadata itself,

+#
+# When the sets are originally created, python calls intern() on the set keys
+# which significantly improves memory usage. Sadly the pickle/unpickle process
+# doesn't call intern() on the keys and results in the same strings being duplicated
+# in memory. This also means pickle will save the same string multiple times in
+# the cache file.
+#
+# By having shell and python cacheline objects with setstate/getstate, we force
+# the object creation through our own routine where we can call intern (via internSet).
+#
+# We also use hashable frozensets and ensure we use references to these so that
+# duplicates can be removed, both in memory and in the resulting pickled data.
+#
+# By playing these games, the size of the cache file shrinks dramatically
+# meaning faster load times and the reloaded cache files also consume much less
+# memory. Smaller cache files, faster load times and lower memory usage is good.

 # A custom getstate/setstate using tuples is actually worth 15% cachesize by

+    2.) The current file creation mode mask set to 0.
+    3.) Close all open files (1024).

+        #    1) When the process that dies is the session leader of a session that
+        #        is attached to a terminal device, SIGHUP is sent to all processes
+        #        in the foreground process group of that terminal device.

-Supported SRC_URI options are:
-
-- module
-   The top-level location to fetch while preserving the remote paths
-
-   The value of module can point to either a directory or a file. The result,
-   in both cases, is that the fetcher will preserve all file paths starting
-   from the module path. That is, the top-level directory in the module value
-   will also be the top-level directory in P4DIR.
-
-- remotepath
-   If the value "keep" is given, the full depot location of each file is
-   preserved in P4DIR. This option overrides the effect of the module option.
