PATCH 1/2 Add mkelfimage and support for generating kernel+initrd ELF payloads to OpenEmbedded

On x86, and ELF image file may be stored as a coreboot payload. This image file may be a kernel or a kernel+initrd.

Documentation on this has been started on the coreboot wiki:
http://www.coreboot.org/Mkelfimage

We have seen success using the mkelfimage utility to construct a kernel+initrd image using the micro-image OpenEmbedded image as an initrd.
http://www.se-eng.com/wiki/index.php/Open_Embedded_Setup

The first patch contains the meta files for the mkelfimage utility in OpenEmbedded.

Please remove that line above. The commit message should be describing the commit only.

Unfortunately we cannot commit your patch, especially because your Signed-off-by line is missing – you can add -s to the Git commands git commit or git format-patch and your mailer mangled the patch by automatic line breaks.

Please follow the commit policy [1] and it would be great if you could send us a corrected patch [2].

Thanks Paul. I am putting together new patches to address your feedback on style guide, mailer line-feed, and patch format/commit policy.

As far as the build configuration this was tested on is concerned, this is Ubuntu 10.04 x86_64-linux targeting i686-oe-linux using a one-off of the i686-generic.conf machine targeting a 4MB flash part.

Thanks again,
Ray

PATCH v2 2/2 conf/bitbake.conf: Add support for generating kernel+initrd ELF coreboot payloads

In reply to Raymond Danks

On x86, and ELF image file may be stored as a coreboot payload. This image file may be a kernel or a kernel+initrd.

Documentation on this has been started on the coreboot wiki:
http://www.coreboot.org/Mkelfimage

We have seen success using the mkelfimage utility to construct a kernel+initrd image using the micro-image OpenEmbedded image as an initrd.
http://www.se-eng.com/wiki/index.php/Open_Embedded_Setup

To use, set a new type "elf" to IMAGE_FSTYPES in conf/local.conf on x86 targets:
IMAGE_FSTYPES = "cpio.gz elf"

You may also override the kernel parameters that are embedded in the elf file:
IMAGE_KERNELPARAMS = "ramdisk_size=32768 root=/dev/ram0 rw console="

The image binary ${TMPDIR}/deploy/images/${MACHINE}/*.elf may be added to the coreboot configuration in Kconfig (CONFIG_PAYLOAD_FILE)
