[PATCH 2/2] 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 second patch contains the necessary commands for adding the image type to bitbake. --- conf/bitbake.conf | 3 +++ 1 files changed, 3 insertions(+), 0 deletions(-)

Dear Raymond,
thank you for your patch!

Please update the summary to just describe the change of this patch. Maybe also add an example command line on how to use the new functionality.

As in the first patch, your Signed-off-by line is missing and your mailer mangled the patch. Please resend as [PATCH 2/2 v2]. (Please always describe changed between patch iterations under the `---`.
Thanks,
Paul
