Intel Firmware Descriptor

[Andy Pont]

Hello,

I’m working on porting Coreboot to a laptop that uses Intel Comet Lake.  
When the build completes it spits out the following warning:

** WARNING **
coreboot has been built without an Intel Firmware Descriptor.
Never write a complete coreboot.rom without an IFD to your
board's flash chip! You can use flashrom's IFD or layout
parameters to flash only to the BIOS region.

What is an IFD and how do I create one?

-Andy.

[coreboot] Intel Firmware Descriptor

Hi Andy,
If you already have a stock bios you can extract it with the ifdtool (ifdtool -x Image.bin). If you are doing a port for a hardware which happened to have no stock bios you need to generate the ifd and me with intels fitc tooling.
Best,
Chris
