[OpenBIOS] [PATCH 00/13] SPARC64: sabre/simba bridge fixups

[Mark Cave-Ayland]

This patchset prepares the way for changing the QEMU sun4u machine to be much
closer to a real Ultra 5.

The main change we are aiming for is to replicate the PCI bus topology so that
onboard devices are attached behind simba A and simba B is an empty PCI bus
(although devices can be added via QEMU's -device syntax).

Note that this patch does all of the preparation work but doesn't actually
implement the changes required by the switch. This is because the QEMU patches
are still awaiting upstream approval and change to the sun4u machine must
be synchronised between QEMU and OpenBIOS.
