#102: flashrom: coreboot ROM image file identification heuristic is broken

Comment(by stuge):
Hold on, this is a bit tricky.
This is about flashrom trying to identify the image it is about to flash.
After identification it checks the vendor/board information in the image
against that in a coreboot table, and will warn the user if the image
seems unsuitable for the board flashrom is running on, and require -f to
override a mismatch.
The fact is that we are having a very hard time coming up with a test
which determines whether an image is coreboot or not to begin with, and
we're also having some difficulties with the technical details of how to
store image metadata in the image itself.
I suggest that we completely remove the image detection for 1.0 and add
the feature back in at a later time when we actually have something close
to a good solution. We have already spent far too much effort on this
problem, and it's sole purpose is to warn users when they are
crossflashing on a board which is running coreboot. I don't think we need
this.
