> Since this commit I'm getting a new "ERROR: FMAP cache corrupted?!" message on AMD f15h and f16h AGESA boards (this message itself also got added with this commit), which luckily doesn't seem to affect anything. If you would like, I could test your newer FMAP changes to see if this could be fixed.

This code assumes C_ENVIRONMENT_BOOTBLOCK. It's easy to fix. OTOH platforms without it will be dropped after the 4.11 release.
