Adding a skeleton/refrence recipe for using a subset of the yocto
kernel tools against kernel git repositories.
Sample/reference configuration fragments, features and a patch are
provided and documented in the recipe.
From the recipe itself:
Provides an example/minimal kernel recipe that uses the linux-yocto
and oe-core kernel classes to apply a subset of yocto kernel
management to git managed kernel repositories.
Notes:
kconfig(s): the kernel must be configured with a defconfig, or via
configuration fragment(s). Either of these can be added
via bbappend.
patches: patches can be merged into to the source git tree itself, added
using standard bbappend syntax or controlled via .scc feature
descriptions (also via bbappends)
example configuration addition:
SRC_URI += "file://smp.cfg"
example patch addition (for kernel v3.4 only):
SRC_URI += "file://0001-linux-version-tweak.patch
example feature addition (for kernel v3.4 only):
SRC_URI += "file://feature.scc"
Warning:
Building the sample kernel tree (kernel.org) without providing any
configuration will result in build or boot errors. This is not a bug
it is a required element for creating a valid kernel.

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 = "") and contains only emulated machine support.
For information about OpenEmbedded, see the OpenEmbedded website:
