* '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.

help
IXP4xx provides two methods of accessing PCI memory space:
1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
1) A direct mapped window from 0x48000000 to 0x4BFFFFFF (64MB).
To access PCI via this space, we simply ioremap() the BAR
into the kernel and we can use the standard read[bwl]/write[bwl]
macros. This is the preferred method due to speed but it
limits the system to just 64MB of PCI memory. This can be
limits the system to just 64MB of PCI memory. This can be
problematic if using video cards and other memory-heavy devices.
2) If > 64MB of memory space is required, the IXP4xx can be
configured to use indirect registers to access PCI This allows
for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
The disadvantage of this is that every PCI access requires
three local register accesses plus a spinlock, but in some
cases the performance hit is acceptable. In addition, you cannot
mmap() PCI devices in this case due to the indirect nature
of the PCI window.
2) If > 64MB of memory space is required, the IXP4xx can be
configured to use indirect registers to access the whole PCI
memory space. This currently allows for up to 1 GB (0x10000000
to 0x4FFFFFFF) of memory on the bus. The disadvantage of this
is that every PCI access requires three local register accesses
plus a spinlock, but in some cases the performance hit is
acceptable. In addition, you cannot mmap() PCI devices in this
case due to the indirect nature of the PCI window.
By default, the direct method is used. Choose this option if you
need to use the indirect method instead. If you don't know

* 1) A direct mapped window from 0x48000000 to 0x4BFFFFFF (64MB).
* To access PCI via this space, we simply ioremap() the BAR

* limits the system to just 64MB of PCI memory. This can be
* problamatic if using video cards and other memory-heavy
* targets.
*
* 2) If > 64MB of memory space is required, the IXP4xx can be configured
* to use indirect registers to access PCI (as we do below for I/O
* transactions). This allows for up to 128MB (0x48000000 to 0x4fffffff)
* of memory on the bus. The disadvantage of this is that every
* PCI access requires three local register accesses plus a spinlock,
* but in some cases the performance hit is acceptable. In addition,
