kernel.bbclass: handle embedding of initramfs images
* "All 2.6 Linux kernels contain a gzipped "cpio" format archive, which is
* extracted into rootfs when the kernel boots up."
* (http://www.kernel.org/doc/Documentation/filesystems/ramfs-rootfs-initramfs.txt)
*
* In some cases it can be useful to take advantage of this ability and embed your
* customized rootfs ("the move to early userspace is necessary because finding
* and mounting the real root device is complex").
*
* Therefore, some code was added and since 2009 OpenEmbedded metadata
* provides a convenient way to include your initramfs by setting
* INITRAMFS_IMAGE = "your_initramfs_image.bb"
* and specifying the chosen output format in the initramfs image recipe, e.g.
* IMAGE_FSTYPES = "cpio.gz cpio.lzma"
*
*
* Patch was imported from the OpenEmbedded git server
* (git://git.openembedded.org/openembedded)
*
* Add satndalone task "builtin_initramfs".
