the code for parsing interrupt maps) to PowerPC and reflect their new MI status by moving them to the shared dev/ofw directory. This commit also modifies the OFW PCI enumeration procedure on PowerPC to allow the bus to find non-firmware-enumerated devices that Apple likes to add, and adds some useful Open Firmware properties (compat and name) to the pnpinfo string of children on OFW SBus, EBus, PCI, and MacIO links. Because of the change to PCI enumeration on PowerPC, X has started working again on PPC machines with Grackle hostbridges. Reviewed by: marius Obtained from: sparc64
