I personally don't have a big problem with the fake PCI stuff. The
spider and USB drivers are already working out of the box pretty much
with PCI and that's exactly what we do on IBM blades (though the
illusion is maintained by the firmware in our case).

I agree that in the long run, it's better to move that to of_platform,
but I wouldn't nack the patches for that.
