On x86, an ELF image file may be stored as a coreboot payload.
The image file is constructed, using the mkelfimage utility,
from a kernel and an initrd.

I guess this was not tested very well, as this failed right out of the
gate.
Thanks for giving this a shot Sau. Could you be more specific regarding
the failure you are seeing?
Sorry, It was Sunday evening and I was a little grumpy at the failure
occuring after all the version.
ERROR: ParseError at
/intel/poky/distro/meta/classes/image_types.bbclass:182: unparsed line:
'ELF_KERNEL ?= ${DEPLOY_DIR_IMAGE}/${KERNEL_IMAGETYPE}'
My guess is because you forgot the quotes on that line, now why I hit it
instantly and you did not see it I am not sure.
bitbake world and it will fail
Please let me know what kind of testing you have done.
This was tested rather exhaustively on an x86_64->x86_64 configuration
prior to the latest changes to the above line. I have only tested this
using the bzImage kernel type. I did feel that I had tested the above
line as well, but it's possible I had something cached somewhere. I'll
kick off a clean build and see if anything surfaces.
Thanks
Sau!
