[PATCH] i386: Some additional chipset register values validation.

Browse source

On i945, a mmconfig range hitting the f0000000-ffffffff zone conflicts
with the APIC registers and others.  Consider it invalid.

On E7520, values 0000 and f000 for the window register are defined
invalid in the documentation.

I haven't seen a bios use these values, but who trusts biosen these
days?
