Raymond Danks - June 29, 2012, 8:19 p.m.
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.

Please let me know what kind of testing you have done.

Thanks

Thanks for giving this a shot Sau.  Could you be more specific regarding 
the failure you are seeing?
>

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.

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

Yes.  I see.  I was using bitbake 1.15.1.  I have updated bitbake to 
current and now see the issue.  I'm submitting an updated version of 
this patch with quotes around this definition.
