I am somewhat concerned about this idea. FExxxxxx seems to be the
"vendor play area" for putting hardware in, FEC even more so.

Can we back out to our original motivation for doing this? I think I
understand it but can we go through it one more time?

As I understand it the idea of moving this around it so limit
restrictions on where initram can be in FLASH -- I'm not sure it would
not make more sense to just tell people "initram must be in high 1 MB"
and leave it at that.

Generality is nice, but taken to extremes it can make life more
complex. See Moon's old essay from long ago (I posted it to the list)
on that topic.

What are we gaining? Do we really need it?
