* 'ixp4xx' of git://git.kernel.org/pub/scm/linux/kernel/git/chris/linux-2.6:
  IXP4xx: GTWX5715 platform only has two PCI IRQ lines, not four.
  IXP4xx: Introduce IXP4XX_GPIO_IRQ(n) macro and convert IXP4xx platform files.
  IXP4xx: move Gemtek GTWX5715 platform macros to the platform code.
  IXP4xx: Remove unused Motorola PrPMC1100 platform macros.
  IXP4xx: move FSG platform macros to the platform code.
  IXP4xx: move DSM G600 platform macros to the platform code.
  IXP4xx: move NAS100D platform macros to the platform code.
  IXP4xx: move NSLU2 platform macros to the platform code.
  IXP4xx: move Coyote platform macros to the platform code.
  IXP4xx: move AVILA platform macros to the platform code.
  IXP4xx: move IXDP425 platform macros to the platform code.
  IXP4xx: Extend PCI MMIO indirect address space to 1 GB.
  IXP4xx: Fix compilation failure with CONFIG_IXP4XX_INDIRECT_PCI.
  IXP4xx: Drop "__ixp4xx_" prefix from in/out/ioread/iowrite functions for clarity.
  IXP4xx: Rename indirect MMIO primitives from __ixp4xx_* to __indirect_*.
  IXP4xx: Ensure index is positive in irq_to_gpio() and npe_request().
  ARM: fix insl() and outsl() endianness on IXP4xx architecture.
  IXP4xx: Fix normally-disabled debugging text in drivers/net/arm/ixp4xx_eth.c.
  IXP4xx: change the timer base frequency to 66.666000 MHz.

           IXP4xx provides two methods of accessing PCI memory space:

              To access PCI via this space, we simply ioremap() the BAR
              into the kernel and we can use the standard read[bwl]/write[bwl]
