This recipe obtains the Zephyr source code tree.
The idea is to use this tree for out-of-tree Zepyhyr images via
DEPENDS += "zephyr-kernel-src"

Setting ZEPHYR_GCC_VARIANT="yocto" will result in images being
built by our own Makefile: Makefile.toolchain.yocto
The Makefile already contains LIB_INCLUDE_DIR definition, so it
can be removed from this recipe.

Zephyr RTOS uses the environmental variable ZEPHYR_GCC_VARIANT to
determine which Makefile to use to build images. This allows different
Makefiles for different toolchains, so the toolchains can co-exist.
Rather than patching the included Makefile.toolchain.zephyr, we use
our own file Makefile.toolchain.yocto. This Makefile will be used as
long as Zephyr recipes set:
export ZEPHYR_GCC_VARIANT="yocto"
(Also removed some BOARD definitions)

Removed the need for "poky.conf", as a consequence
some variables previously defined via poky.conf needed to
be re-defined: TARGET_VENDOR, TCLIBCAPPEND
Moved here default BOARD definitions.
Defined DISTRO_VERSION.

Do not prepend 'test' to test programs.
(Don't assume all test programs names begin with 'test_')

Remove tests that fail because QEMU for ARM does not emulate
CortexM3 BASEPRI register functionality.

Cortex-M3 is not supported natively by oe-embedded, so we need to
do it here. With these changes it should be possible to run:
To build all Zephyr tests:
$ MACHINE=qemuarm bitbake zephyr-kernel-test-all
$ MACHINE=qemuarm bitbake zephyr-kernel-test-all -ctestimage
To build "philosophers" sample:
$ MACHINE=qemuarm bitbake zephyr-philosophers
Once built, you can run the created "philosophers" image in qemu
(at this point the various paths have to be entered manually):
$ ./tmp/sysroots/x86_64-linux/usr/bin/qemu-system-arm \
-kernel ./tmp/deploy/images/qemuarm/philosophers.elf \
-cpu cortex-m3 -machine lm3s6965evb -nographic -vga none

Numerous changes to allow building and running various
Zephyr tests using Zephyr release 1.6 and Yocto master distro
(commit 3676601335b4673e3572d5a9987a351f0bb44bcb and later)
Work in progress.
Notable changes:
1. Zephyr 1.6 does not support the concept of nano and micro kernel
anymore.
2. Location of various tests have changed
3. Changes due to subtle python3/python2 differences
4. Zephyr Makefile changes (including renaming)
5. Improved failed test detection
6. Remove patch files no longer needed
With these changes, it is now possible to run Zephyr test suite and
Zephyr sample programs. Currently only x86 CPUs are supported, with
additional CPU support coming in the near future, in particular
support for ARM Cortex-M3 CPUs
Prerequisites:
Modify local conf by adding:
DISTRO="zephyr"
MACHINE?="qemux86"
Modify bblayers.conf by adding "meta-zephyr" to BBLAYERS
To build all Zephyr tests:
$ bitbake zephyr-kernel-test-all
To test all built test images:
$ bitbake zephyr-kernel-test-all -ctestimage
You can also build and test an individual test. This is done by appending
the actual test name to the "zephyr-kernel-test", for example:
$ bitbake zephyr-kernel-test-test_sleep
$ bitbake zephyr-kernel-test-test_sleep -ctestimage
It is also possible to build Zephyr sample programs. Included is a sample recipe
that builds the Zephyr "philosophers" sample:
$ bitbake zephyr-philosophers
Once built, you can run the created "philosophers" image in qemu (at this point
the various paths have to be entered manually):
$ ./tmp/sysroots/x86_64-linux/usr/bin/qemu-system-i386 \
-kernel ./tmp/deploy/images/qemux86/philosophers.elf \
-nographic -machine type=pc-0.14 -display none -clock dynticks \
-no-acpi -balloon none
