* respect all 4 vfp options ('vfp', 'vfpv3d16', 'vfpv3', 'vfpv4') when
setting -mfloat-abi and ARMPKGSFX_EABI, without this change it wasn't
possible to use call-convention hard together with vfpv4
* move 'vfpv3d16', 'vfpv3', 'vfpv4' support from
feature-arm-vfp.inc
to
feature-arm-neon.inc
the main difference is that feature-arm-vfp.inc is included in
arch-armv5.inc while feature-arm-neon.inc only in armv7*.inc, so
these options should be added to TUNEVALID also only for armv7*
MACHINEs.
* support vfpv4 with or without neon
when both vfpv4 and neon are in TUNE_FEATURES we want to set only one
-mfpu parameter and to neon-vfpv4
* prevent multiple appends to ARMPKGSFX_FPU, we don't want to include
e.g. -vfp as well as -vfpv4 when both "vfp" and "vfpv4" are in
TUNE_FEATURES
* add -mfpu=vfp for tunes with "vfp" in TUNE_FEATURES - before that we
were only adding -vfp to ARMPKGSFX_FPU
* add TUNE_CCARGS_MFPU variable which is used to set -mfpu parameter as
well as ARMPKGSFX_FPU suffix in TUNE_PKGARCH, all enabled values are
appended to it based on TUNE_FEATURES and then the last one is used
in the actual param and suffix
* this prevents multiple -mfpu options in TUNE_CCARGS
* !!!
This means we need to change TUNE_PKGARCH and PACKAGE_EXTRA_ARCHS for
vfpv4, vfpv3d16, vfpv3 tunes, because the -vfp* isn't prependend
multiple times. If you're using one of these new DEFAULTTUNES (which
were at least partially broken anyway) and depend on working binary
package feed upgrade-path, then don't forget to migrate PR service
database to new TUNE_PKGARCH.

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 (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
bitbake: Git repository: http://git.openembedded.org/bitbake/ Mailing list: bitbake-devel@lists.openembedded.org
documentation: Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/ Mailing list: yocto@yoctoproject.org
meta-yocto(-bsp): Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp) Mailing list: poky@yoctoproject.org
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.
Git repository: http://git.openembedded.org/openembedded-core/
Mailing list: 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.
