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?
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!
