Convert the 'choice' into a 'menu' to allow multiple platforms to be

This means to do a build check across PXA, you don't end up spending

Patch mainly from Eric Miao, with minor edits by rmk.
Note: PWM0 and PWM2 share the same register I/O space and clock gating
on pxa{27x, 3xx}, thus PWM2 is treated in the driver as a child PWM of
PWM0. And this is also true for PWM1/3.

This patch adds baseboard support for the phyCORE-PXA270 development
kit (aka PCM-990).
This example shows how to use some phyCORE-PXA270 CPU module features
on a baseboard in a standard manner. It could be used as a starting
point for custom baseboard development.

After comments by Eric Miao:
- IRQ chained handler fixed
- video/graphic support moved to separate patch
- ifdef/endif hell reduced ;-)

After comments by Russell King
- initialise the mmci platform data statically

This patch adds main support for the generic phyCORE-PXA270 CPU module
(aka PCM-027). Its as generic as possible to support any kind of baseboard.
Note: Neither the CPU module nor the pcm027.c implementation can work without
a baseboard support. Baseboard support can be added by the PCM-990 or any
custom variant.
V2:
After comments by Eric Miao:
- Currently unsupported devices moved into separate patch
- direct call of baseboard initialisation
V3:
After comments by Russell King
- sort include files
- setting RTC bit for power control removed
- style problems fixed (discovered by checkpatch.pl)

XScale cores either have a DSP coprocessor (which contains a single
40 bit accumulator register), or an iWMMXt coprocessor (which contains
eight 64 bit registers.)
Because of the small amount of state in the DSP coprocessor, access to
the DSP coprocessor (CP0) is always enabled, and DSP context switching
is done unconditionally on every task switch. Access to the iWMMXt
coprocessor (CP0/CP1) is enabled only when an iWMMXt instruction is
first issued, and iWMMXt context switching is done lazily.
CONFIG_IWMMXT is supposed to mean 'the cpu we will be running on will
have iWMMXt support', but boards are supposed to select this config
symbol by hand, and at least one pxa27x board doesn't get this right,
so on that board, proc-xscale.S will incorrectly assume that we have a
DSP coprocessor, enable CP0 on boot, and we will then only save the
first iWMMXt register (wR0) on context switches, which is Bad.
This patch redefines CONFIG_IWMMXT as 'the cpu we will be running on
might have iWMMXt support, and we will enable iWMMXt context switching
if it does.' This means that with this patch, running a CONFIG_IWMMXT=n
kernel on an iWMMXt-capable CPU will no longer potentially corrupt iWMMXt
state over context switches, and running a CONFIG_IWMMXT=y kernel on a
non-iWMMXt capable CPU will still do DSP context save/restore.
These changes should make iWMMXt work on PXA3xx, and as a side effect,
enable proper acc0 save/restore on non-iWMMXt capable xsc3 cores such
as IOP13xx and IXP23xx (which will not have CONFIG_CPU_XSCALE defined),
as well as setting and using HWCAP_IWMMXT properly.

This patch allows users of the pxa SSP driver to register their own irq
handlers instead of using the default SSP handler. It also cleans up the
CKEN clock and irq detection as the values are now stored in a table.
This patch replaces 2845/1
Changes:-
o Added flags parameter to ssp_init()
o Added SSP_NO_IRQ flag to disable registering of ssp irq handler (for
drivers that want to register their own handler)
o Cleaned up clock and irq detection, values are now stored in table.
o Added build changes to allow other drivers (e.g audio) to select the
ssp driver.
o corgi_ssp.c changed to use new interface.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
