Depends which part. Not -all- of our PCI code as John seems to want.

The bits that generate PCI devices from the device-tree, for sure,
though again, even there, there are quite a few dependencies on
constructs and data structures that are powerpc specific, or even ppc64
specific in some cases, and that would have to be cleaned up and/or
abstracted first.

Cheers,
Ben.
