This patch set fixes an opps when loading the radeon driver on old Macs
with a 32-bit EFI implementation.

Tested on a MacPro 1,1 with a Radeon X1900 XT card and 32-bit kernel.

Mikel Rychliski (4):
  drm/radeon: Stop directly referencing iomem
  PCI: Use ioremap, not phys_to_virt for platform rom
  drm/radeon: iounmap unused mapping
  drm/amdgpu: iounmap unused mapping
