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

(with support for more AT91 processors pending), the "mach-at91rm9200"

more generic nature.
The following git commands should be run BEFORE applying this patch:

Fix build failure of AT91SAM9260.
The AT91RM9200 ethernet driver (at91_ether.c) stores platform data in a
"struct at91_eth_data" structure, but the AT91SAM9260 (and AT91SAM9263)
ethernet driver (macb.c) [developed on the AVR32 architecture] expects a
"struct eth_platform_data".
Since the platform data of the two drivers is very similar, we continue
to use the "struct at91_eth_data" for all AT91 processors but add a
#define eth_platform_data at91_eth_data
in board.h to keep the MACB driver happy.

Memory allocated by the coherent memory allocators will be marked
uncacheable, which means it's pointless calling consistent_sync()
to perform cache maintainence on this memory; it's just a waste of
CPU cycles.
Moreover, with the (subsequent) merge of outer cache support, it
actually breaks things to call consistent_sync() on anything but
direct-mapped memory.

The architecture specification states that TLB operations are
guaranteed to be complete only after the execution of a DSB (Data
Synchronisation Barrier, former Data Write Barrier or Drain Write
Buffer). The branch target cache invalidation is also needed. The ISB
(Instruction Synchronisation Barrier, formerly Prefetch Flush) is
needed unless there will be a return from exception before the
corresponding mapping is used (i.e. user mappings).

On newer architectures (ARMv6, ARMv7), the depth of the prefetch and

of wrong ASID tagging when changing TTBR0 before setting the new

TTBR changing. This patch reserves ASID 0.

This patch cleans up proc-xsc3:
- Correct a number of typos.
- Fix up indentation in a number of places.
- Change references to the various caches to be more clear about
whether we're talking about the L1 D, the L1 I or the unified L2
cache.
- Rename "drain write buffer" to "data write barrier", the official
name used in the Manzano manual.
- Change the xsc3 cpu name from "XScale-Core3" to "XScale-V3 based
processor".
Also, since a previously merged patch implements proper support for
using a MAC or iWMMXt coprocessor on xsc3 platforms, we no longer
need to enable access to CP0 on boot.

The arch hooks arch_setup_msi_irq and arch_teardown_msi_irq are now
responsible for allocating and freeing the linux irq in addition to
setting up the the linux irq to work with the interrupt.
arch_setup_msi_irq now takes a pci_device and a msi_desc and returns
an irq.

except those that won't let the OS touch the hardware like ppc RTAS.

We need to be able to get from an irq number to a struct msi_desc.
The msi_desc array in msi.c had several short comings the big one was
that it could not be used outside of msi.c. Using irq_data in struct
irq_desc almost worked except on some architectures irq_data needs to
be used for something else.
So this patch adds a msi_desc pointer to irq_desc, adds the appropriate
wrappers and changes all of the msi code to use them.
The dynamic_irq_init/cleanup code was tweaked to ensure the new
field is left in a well defined state.

When we do full FP emulation its possible that we need to post a SIGFPE based
on the results of the emulation. The previous code ignored this case completely.
Additionally, the Soft_emulate_8xx case had two issues. One, we should never
generate a SIGFPE since the code only does data movement. Second, we were
interpreting the return codes incorrectly, it returns 0 on success, 1 on
illop and -EFAULT on a data access error.

Anytime we are emulating an instruction we are going to be doing some form of
get_user() to get the instruction image to decode. Since get_user() might
sleep we need to ensure we have interrupts enabled or we might see something
like:
