Integrated GPU will be initialized and will be working perfectly even
if we are not doing the VFCT for it! :-) Aside from one angry
"[drm:radeon_get_bios [radeon]] *ERROR* ACPI VFCT image header
truncated" message at Linux kernel logs (see the end of this message)
we have not noticed any downsides from doing the ACPI VFCT tables for
G505S discrete GPU only instead of integrated.

So both integrated and discrete GPU of G505S are now working fine with
these three coreboot patches ( 31448 / 31449 / 31450 ). Although it is
a bit disappointing to see they have not been received well, I will
continue working on them and hopefully they would be merged to
coreboot master one day. Meanwhile I could write a small script that
will be securely downloading and applying them, just like we are
already doing for the "15h / 16h updated microcode" changes.

Best regards,
Mike Banon
