Yes. flashrom should know CBFS.

I see a few problem with normal and fallback as they have been in v2
It was not well understood how to produce them. It was not well
understood how they were combined. And finally it was not well
understood how one of the two were selected.
CBFS and Kconfig fixes the hard parts; the first two.
I see cbfstool being a crucial part of safe updates. Initially
cbfstool might have to be run manually (or even just flashrom) but
we should look into how Kconfig and the build system can take an
existing CBFS as input, and only build/replace the normal part.

Two directories strikes me as pretty complicated but I do get your
point - it should be really easy to rebuild and flash normal, without
touching anything else.
