This patch series fixes an oops 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.

Changes in v2:
 - Add iounmap() call in nouveau
 - Update function comment for pci_platform_rom()
 - Minor changes to commit messages

Mikel Rychliski (2):
  drm/radeon: Stop directly referencing iomem
  PCI: Use ioremap(), not phys_to_virt() for platform ROM
