[SPARC64]: Consolidate PCI mem/io resource determination. It can be done for every PCI configuration using OF properties. Signed-off-by: David S. Miller <davem@davemloft.net>

/* pci_impl.h: Helper definitions for PCI controller support.
Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[SPARC64]: Convert sparc64 PCI layer to in-kernel device tree. One thing this change pointed out was that we really should pull the "get 'local-mac-address' property" logic into a helper function all the network drivers can call. Signed-off-by: David S. Miller <davem@davemloft.net>

[SPARC64]: Internalize pci_memspace_mask. The only user was bus_dvma_to_mem() which is no longer used by any driver, so kill that, and the export of pci_memspace_mask. The only user now is the PCI mmap support code. Signed-off-by: David S. Miller <davem@davemloft.net>

[SPARC64]: Add dummy host controller to root of all PCI domains. We fake up a dummy one in all cases because that is the simplest thing to do and it happens to be necessary for hypervisor systems. Signed-off-by: David S. Miller <davem@davemloft.net>
