[Qemu-devel] [PATCH] hw/pci-host/uninorth.c: Add support for Apple's PCI bridge register 0x48

[Programmingkid <programmingkidx@gmail.com>]

Apple has custom PCI bridge registers that are not a part of any known standard. This patch implements register 0x48. With this patch the AppleMacRiscPCI kernel extension no longer prints these error messages for the mac99 target:
AppleMacRiscPCI: bad range 2(80000000:01000000)
AppleMacRiscPCI: bad range 2(81000000:00001000)
AppleMacRiscPCI: bad range 2(81080000:00080000)
