This branch contains two kinds of updates: Some platforms in the process
of getting converted to device tree based booting, and the platform
specific patches necessary for that are included here. Other platforms
are already converted, so we just need to update the actual device
tree source files and the binding documents to add support for new board
and new drivers.
In the future we will probably separate those into two branches, and
in the long run, the plan is to move the device tree source files out
of the kernel repository, but that has to wait until we have completed
a much larger portion of the binding documents.

MULTI_IRQ_HANDLER and SPARSE_IRQ are now required everywhere because
mach/irqs.h and mach/entry-macros.S are gone but the symbols are
only selected for AT91SAM9, not for the NOMMU parts.
A few files now need to include linux/io.h directly, which used to
be included through other headers that have changed.
The new at91_aic_irq_priorities variable is only used with CONFIG_OF
enabled and should not be visible otherwise.

The number of lines of AIC5 has increased from 32 to 128. Due to this
increase, a source select register has been introduced for the interrupt
line selection. Moreover, register mapping has been changed. For that reasons,
we need some dedicated callbacks for AIC5.
Power management is also concerned by these changes. On suspend, we can't get
the whole interrupt mask register as before, we have to read this register 128
times. To reduce this overhead, a snapshot of the whole IMR is maintained.

Commit 82c583e3ae ("AT91RM9200 hardware
headers") introduced arch/arm/mach-at91/include/mach/at91_spi.h and
arch/arm/mach-at91/include/mach/at91_ssc.h. (These files were called
at91rm9200_spi.h and at91rm9200_ssc.h then.) That commit was added in
the v2.6.18 development cycle.
Nothing includes them now and nothing uses the named constants they
provide. (There's no way these named constants could be used unless
these files were included somehow.) It actually seems these two headers
have never been used since they were added to the tree. They can safely
be removed.

Here is the big staging tree pull request for the 3.5-rc1 merge window.
Loads of changes here, and we just narrowly added more lines than we
added:
622 files changed, 28356 insertions(+), 26059 deletions(-)
But, good news is that there is a number of subsystems that moved out of
the staging tree, to their respective "real" portions of the kernel.
Code that moved out was:
- iio core code
- mei driver
- vme core and bridge drivers
There was one broken network driver that moved into staging as a step
before it is removed from the tree (pc300), and there was a few new
drivers added to the tree:
- new iio drivers
- gdm72xx wimax USB driver
- ipack subsystem and 2 drivers
All of the movements around have acks from the various subsystem
maintainers, and all of this has been in the linux-next tree for a
while.

The AT91RM9200 Ethernet controller still has a fixed IO mapping.
So:
* Remove the fixed IO mapping and AT91_VA_BASE_EMAC definition.
* Pass the physical base-address via platform-resources to the driver.
* Convert at91_ether.c driver to perform an ioremap().
* Ethernet PHY detection needs to be performed during the driver
initialization process, it can no longer be done first.

We can now compile all SoC core support together and DT boards.
We still can not compile together the non DT board.
So We keep the ARCH_AT91xxx for the non DT board and for backward defconfig
compatibility. This will enable the plaform_device ressources.

at91_set_serial_console is used to define the default console of linux.
This is already manage by the cmdline. And if the boot loader can not be
modified you can still set it by enabling the CONFIG_CMDLINE_EXTEND option.
And then the command-line arguments provided by the boot loader will be
appended to the default kernel command string.

This will now autodetect the first uart enabled by the bootloader
and will use it for uncompress. This will still assume that the bootloader
configured it (pins and clock).
This also allows to include all soc headers together.
