From: Daniel Vetter <daniel.vetter@xxxxxxxx>
A few reasons for this:
- It's really the only one where this matters. I tried looking around,
and I didn't find any non-pci vga-compatible controllers for x86
(since that's the only platform where we had this until a few
patches ago), where a driver participating in the aperture claim
dance would interfere.
- I also don't expect that any future bus anytime soon will
not just look like pci towards the OS, that's been the case for like
25+ years by now for practically everything (even non non-x86).
- Also it's a bit funny if we have one part of the vga removal in the
pci function, and the other in the generic one.
v2: Rebase.
v4:
- fix Daniel's S-o-b address
