These mostly are cleanups up to pci bus scan amendment changes.
The pci bus scan is reworked, now we start with pci host bridge which will initiate primary bus scan. PCI-to-PCI bridges do the same.
Although bridges are still mostly unusable in qemu due to missing address space remappings one can now put e.g. ide and vga on sun4u behind secondary bus and see it is found correctly and can be configured.
With these applied my debian etch ppc installation still boots to shell, and helenos can get to video screen (with appropriate QEMU,VGA driver.) Another bonus point that on sparc64 recent linux "btext" boot console works (colors are a bit off though.)

Thanks for the patchset - this is great progress! Overall the patch looks reasonably sensible to me, but will defer to Blue for technical feedback and commit.
I also think they are very nice, I'll have to run a few tests though.
