The Atmel AT91SAM9263 processor includes many more integrated
peripherals than Atmel's previous ARM9-based AT91 processors, so this
has necessitated a few changes to the core AT91 support.

These changes are:
      * The system peripheral I/O region we remap has increased from
        0xFFFA0000..0xFFFFFFFF to 0xFFF78000..0xFFFFFFFF.
      * The increased I/O region forces changes to entry-macro.S and
        debug-macro.S due to ARM's limited immediate offset addressing
        modes.
      * Maximum number of GPIO banks increases to 5.
      * 2 MMC controllers so the board-setup code needs to specify which
        controller it wishes to use when calling at91_add_device_mmc().

Now that Linux includes support for the Atmel AT91SAM9260 and
AT91SAM9261 processors in addition to the original Atmel AT91RM9200
(with support for more AT91 processors pending), the "mach-at91rm9200"
and "arch-at91rm9200" directories should be renamed to indicate their
more generic nature.

The following git commands should be run BEFORE applying this patch:
  git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91
  git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91

This patch makes the AT91 gpio.c support processor-generic (AT91RM9200
and AT91SAM9xxx).  The GPIO controllers supported by a particular AT91
processor are defined in the processor-specific file and are registered
with gpio.c at startup.

This is more preparation for adding support for the new Atmel AT91SAM9
processors.

Changes include:
- Replace AT91_BASE_* with AT91RM9200_BASE_*
- Replace AT91_ID_* with AT91RM9200_ID_*
- ROM, SRAM and UHP address definitions moved to at91rm9200.h.
- The raw AT91_P[ABCD]_* definitions are now depreciated in favour of
the GPIO API.

Patch from Andrew Victor

This patch adds the core Power Management support for the AT91RM9200
processor.  It will support suspend-to-RAM and standby modes.

The suspend-to-RAM functionality is not 100% complete.  The code that
needs to be execute from the internal SRAM to restore the system is
outstanding.  For now we just fall through to Standby mode.

The AT91-specific at91_suspend_entering_slow_clock() function will
eventually be replaced by clk_must_disable() once that functionality is
added to mainline clock API.

Patch from Andrew Victor

This patch adds the at91_set_multi_drive() function to enable/disable
the multi-drive (open collector) pin capability on the AT91RM9200
processor.

This is necessary to fix the UDC (USB Gadget) driver for the AT91RM9200
board as it will not allow the board reset line to be pulled low if the
pullup is not driven as an open collector output as the boards are wired
to the USB connector on both the DK/EK.

This version of the patch updates it to 2.6.16-rc4.

Patch from SAN People

Following changes were made to clock.c:

1) Replaced <asm/hardware/clock.h> with <linux/clk.h>
2) Removed old unused clk_enable & clk_disable.
3) Replaced clk_use/clk_unuse with clk_enable/clk_disable.

Otherwise it's the same as the previous patch.
