Well, realistically the segment size should be 8MB to make this matter
(or the whole window 2GB) which does not seem to happen so it does not
matter.

I'm not sure what you mean.

I mean how can we possibly hit this case, what m64_segsize would the
platform have to trigger this. The whole check seems useless but whatever.

Yeah maybe.

IIRC some old P8 FSP systems had tiny M64 windows so it might have
been an issue there. Maybe we can get rid of it., but I'd rather just
leave the behaviour as-is for now.
