Patch from Lennert Buytenhek
Analogous to the previous patch that allows ioremap() to use section
mappings, this patch allows ioremap() to use supersection mappings.

This patch adds support for the Cirrus Logic EDB9315A, an evaluation
board based on the Cirrus Logic EP9315 SoC, with 64M RAM, two USB host
ports, audio in/out, three serial ports, 10/100 ethernet, and IDE, VGA,
and LCD interfaces.
The EDB9315A is a low-cost version of the EDB9315, and has only 16M
of NOR flash, while the EDB9315 has 32M.

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.

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 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
were not) selected at kernel build time. Rather than have every
proc-*.S file implement this, report the control register value,
from which this information can be deduced.

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]".
[ This is just an alternate and simpler patch to one proposed by Andrew
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.
