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

[Liviu Dudau]

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/)
