Yes, we do that in arch/powerpc/kernel/pci_64.c (and somewhere in
arch/sparc too). I'll merge those 2 implementations one of these days
and move them to drivers/of.

I think Willy was actually suggesting that you start using our
OF/device-tree stuff though which is a slightly more invasive deal but
might end up useful for other things in the long run :-)
