I'd like to see what this would look like with actual ARM support,
rather than just some theoretical attempts to make it less PPC-dependent
that involve copying PPC stuff that may or may not work well with what
ARM code will expect.
When I replied to Kumar's comment saying that this seemed like a
reasonable interim approach, that was before I saw how much was copied
from places other than fsl_pci files.
