* Modification of Kconfig to add the Option
* 1 new file : buffalo-wxl-setup.c
This file is inspired from the db-78xx0-setup.c already present.
The following is done:
- Configure MPP Lines for the plateform (see my patch for MPP)
This is taken from the stock kernel provided by buffalotech (the vendor)
- GigaBit Ethernet
- Sata
- Uart are initiallized in a different way than on the dev board as we
have one core only.
- USB
The kernel has been running for some days now on my plateform.

This patch is composed of two new files :
- mpp.c which is mainly inspired by the same file as in mach-kirkwood
- mpp.h that is written from the documentation provided by Marvell
http://www.marvell.com/products/processors/embedded/discovery_innovation/HW_MV78100_OpenSource.pdf
Moreover, due to some implementation problem, I have
defined some MPPX_UNUSED that offer developers the possibility
to SET MPP to some unused value (such as for Buffalo WXL).
Note: This patch doesn't support MV78200 yet (only 78100 MPP lines have
been written)

The 'outer_cache' variable is needed by the outer_inv_range(),
outer_clean_range() and outer_flush_range() functions, which are
declared as inline in asm/cacheflush.h. Otherwise drivers built
as a loadable module, which access these functions, will have
an undefined symbol.

This patch fixes the power LED on DNS-323 revision A1, and adds timer
support for (hopefully) both A1 and B1 revisions.
Power LED on revision A1 is active low and also requires GPIO 4 to be
low to work.
Tested on my DNS-323 revision A1.
I have set the default trigger to timer as that replicates the
behaviour of the original firmware, userspace can change the trigger
at the end of the boot process providing a useful indication that
booting has completed.

Currently the omap serial clocks are autoidled after 5 seconds.
However, this causes lost characters on the serial ports. As this
is considered non-standard behaviour for Linux, disable the timeout.
Note that this will also cause blocking of any deeper omap sleep
states.
To enable the autoidling of the serial ports, do something like
this for each serial port:
# echo 5 > /sys/devices/platform/serial8250.0/sleep_timeout
# echo 5 > /sys/devices/platform/serial8250.1/sleep_timeout

3630 has more mux signals than 34xx. The additional pins
exist in omap36xx_cbp_subset, but are not initialized
as the superset is missing these offsets. This causes
the following errors during the boot:
mux: Unknown entry offset 0x236
mux: Unknown entry offset 0x22e
mux: Unknown entry offset 0x1ec
mux: Unknown entry offset 0x1ee
mux: Unknown entry offset 0x1f4
mux: Unknown entry offset 0x1f6
mux: Unknown entry offset 0x1f8
mux: Unknown entry offset 0x1fa
mux: Unknown entry offset 0x1fc
mux: Unknown entry offset 0x22a
mux: Unknown entry offset 0x226
mux: Unknown entry offset 0x230
mux: Unknown entry offset 0x22c
mux: Unknown entry offset 0x228
Fix this by adding the missing offsets to omap3 superset.
Note that additionally the uninitialized pins need to be
skipped on 34xx.

OMAP platforms(like OMAP3530) include DSP or other co-processors
for media acceleration. when carving out memory for the
accelerators we can end up creating a hole in the memory map
of sort:
<kernel memory><hole(memory for accelerator)><kernel memory>
To handle such a memory configuration ARCH_HAS_HOLES_MEMORYMODEL
has to be enabled. For further information refer discussion at:

Current behaviour is to generate the IT instruction only for Thumb-2
code. However, the kernel helpers in entry-armv.S are compiled to ARM in
a unified syntax file (if THUMB2_KERNEL). Recent compilers warn about
missing IT instruction in unified assembly syntax files. The patch
changes the "-mimplicit-it" gas option to "always".

This patch fixes power LED blinking and power-off on DNS-323 rev. B1.
GPIO pin 3 has to be set to 1 to stop power LED blinking and to allow the LED to be controlled via leds-gpio. This pin has to be also set to 1 for power-off to work.
To power-off the rev. B1 machine, pin 8 has to be set to 1 and then set to 0 to do actual power-off.
