The problem is worse when one thinks about software sequencing
which we used on some platforms (I guess until Intel shut it down
with SKL), and have to use on pre-ME-enforced platforms. So there
is definitely more to test.

I suggest that you go on with this and we bring older platforms
up to speed one by one. We just have to make sure that the Kconfig
changes don't break the flash console.
