Just drop ifdfake and related functions in our Kconfig/Makefiles. It's
purpose relies on a patch to flashrom that was never merged and even its
author (me) doesn't use it any more. The idea was to have the region
table in the image to verify it against the descriptor in flash. IMO,
flashrom should use the in flash descriptor by default and only support
a different layout when explicitly asked to overwrite the descriptor. So
you wouldn't usually need any descriptor in the coreboot image.

flashrom/ich_descriptors.[ch] might also be a good reference.

However, I believe as long as a user can't verify the code of such a
tool against some official documentation, he has not only to trust
the chip vendors + OEM but also the author of such a tool to run his
machine. You'll just exchange a blob for a blob.
