A change in QEMU on how PCI bridges are setup revealed a bug in OpenBIOS PCI setup. On Sparc64, the BARs just happened to get somewhat correct values by accident before the commit but not after the change.
Avoid to set up BARs for host bridge. Fix bridge check, this lead to setting up 6 BARs instead of more correct 2. If a bridge doesn't have any devices behind it, disable it entirely. Fix Sparc64 PCI memory base.

I confirm that this patch appears to fix the problem for me, although I guess there may be some further related bridge changes based on the current thread with Michael?
