Andrew Morton found a section mismatch warning in x86_64 triggered by a
wrongly placed __initdata marker.

git grep "struct __initdata" revealed that board-sam9260.c had the same
problem.

This patch fixes this by placing the __initdata marker correct.  It was
checked with objdump that the variable was moved to .init.data by this
change.

Fixed an unrelated section mismatch warning while touching the file.

Both changes are only compile tested but obvious correct.

Fix the NAND flash timings on the AT91SAM9260.

The current timings lead to the detection of a number of bad blocks.
These timings are now set the same as on the AT91SAM9263.

It's been pointed out that output GPIOs should have an initial value, to
avoid signal glitching ...  among other things, it can be some time before
a driver is ready.  This patch corrects that oversight, fixing

 - documentation
 - platforms supporting the GPIO interface
 - users of that call (just one for now, others are pending)

There's only one user of this call for now since most platforms are still
using non-generic GPIO setup code, which in most cases already couples the
initial value with its "set output mode" request.

Note that most platforms are clear about the hardware letting the output
value be set before the pin direction is changed, but the s3c241x docs are
vague on that topic ...  so those chips might not avoid the glitches.

Add support for the Atmel AT91SAM9XE range of processors.  These are
basically AT91SAM9260's with different amounts of internal SRAM and
Flash.

We make use of the existing AT91SAM9260 support, but just perform
run-time detection of the size of the internal SRAM.

Unconditionally disabling the PCKs (Programmable Clocks) is not a good
idea as it breaks boards that depend on those clocks being enabled by
bootloaders.
Therefore only disable unused clocks late in the init process, giving
the board init code the chance to claim the clock.

Patch from Steven Scholz.

Since the HCK clocks on SAM9261 are already being registered as a
independent clocks, we don't need the special case for HCK0 on the
SAM9261.  Platform-init code and drivers should use the clock API to
enable/disable the clock.

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.

  git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91
  git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91
