Subject: [PATCH v13 00/12] Support for creating generic PCI host bridges from DT

This is my version 13 of the attempt at adding support for generic PCI host
bridge controllers. It contains only cleanups to make it play nice with the
linux-next tree as of 09/25. If Bjorn deems it safe, now that it looks like
asm-generic is going to revert some of its more aggresive patches, he has the
choice of queueing it into linux-next again.

Changes from v12:
- refreshed the whole series based on what Bjorn has submitted into linux-next.
  He has added Signed-off-bys and change the title of some commits, plus
  reworked the patches that move of_pci_range_to_resource() from of_address.h into
  address.c.
- updated "[PATCH 01/12] asm-generic/io.h: Fix ioport_map() for !CONFIG_GENERIC_IOMAP"
  to match the patch that Thierry Reding has submitted through the asm-generic branch.
  If his series lands first upstream this patch will be skipped.
- updated "[PATCH 03/12] ARM: Define PCI_IOBASE as the base of virtual PCI IO space" to
  cast the PCI_IOBASE value to (void __iomem *) as is the case with most #defined versions
- dropped the patch that was changing the order of initialisation between pci_host_bridge
  and root bus in pci_create_root_bus()
- fixed "[PATCH 07/12] PCI: Add generic domain handling" to account for the previous patch
  being removed
- fixed the title of commit 08/12 to reflect the name of the functions that are actually
  added (s/of_pci_get_domain_nr/pci_get_new_domain_nr/)
