Allow section mappings to be setup using ioremap() and torn down
with iounmap().  This requires additional support in the MM
context switch to ensure that mappings are properly synchronised
when mapped in.

Based an original implementation by Deepak Saxena, reworked and
ARMv6 support added by rmk.

Avoid folk having to edit cpu-sa1110.c to select their RAM type;

On some CPUs, bit 4 of section mappings means "update the
cache when written to".  On others, this bit is required to
be one, and others it's required to be zero.  Finally, on
ARMv6 and above, setting it turns on "no execute" and prevents
speculative prefetches.

With all these combinations, no one value fits all CPUs, so we
have to pick a value depending on the CPU type, and the area
we're mapping.

Patch from Andrew Victor

This prepares the way for adding support for the new Atmel AT91SAM926x
processors.

Major changes:
- Rename time.c to at91rm9200_time.c
- Rename common.c to at91rm9200.c
- Introduce ARCH_AT91, of which ARCH_AT91RM9200, ARCH_AT91SAM9260 and
ARCH_AT91SAM9261 are dependent.

Patch from Lennert Buytenhek

The bootloader on the LogicPD PXA270 platform informs the kernel of
which type of TFT screen is connected via an lcd=$FOO kernel command
line parameter.

Before this patch, we ignored this parameter and just hardcoded the use
of the Sharp lq64d343 display kit.  This patch implement parsing of the
command line option, and chooses the right pxafb_mach_info to use (six
choices) based on this command line option.

Also fix the fb settings to correspond with those of the bootloader.

The "id(wb)BRR" suffix reports which CPU debugging options were (or

The recent vsnprintf() fix introduced an off-by-one, and it's now
possible to overrun the target buffer by one byte.

The "end" pointer points to past the end of the buffer, so if we
have to truncate the result, it needs to be done though "end[-1]".

  and Jeremy, who actually noticed the problem ]

This patch adds earlier initialization of spi_device.mode, as needed
on boards using nondefault chipselect polarity.  An example would be
ones using the RS5C348 RTC without an external signal inverter between
the RTC chipselect and the SPI controller.

Without this mechanism, the first setup() call for that chip would
wrongly enable chips, corrupting transfers to/from other chips sharing
that SPI bus.
