This series reworks the IXP4xx PCI driver. The plan is the
following:

- Implement a new proper host controller that is just used
  when booting IXP4xx from device tree. (This patch series.)
- Delete all boardfiles.
- Delete the old PCI driver in arch/arm/mach-ixp4xx.
- Only device tree and proper PCI driver remains.

Linus Walleij (4):
  ARM/ixp4xx: Move the UART and exp bus virtbases
  ARM/ixp4xx: Make NEED_MACH_IO_H optional
  PCI: ixp4xx: Add device tree bindings for IXP4xx
  PCI: ixp4xx: Add a new driver for IXP4xx
