Patch from Catalin Marinas
AACI reports TX FIFO full after the first write to it if the AC97 is not
enabled. This patch enables the AC97 probing before the check for the TX
FIFO size. The patch also adds a warning if the TX FIFO size is not
multiple of 16.

Since the ARM AMBA bus is used on MIPS as well as ARM, we need
to make the bus available for other architectures to use. Move
the AMBA include files from include/asm-arm/hardware/ to
include/linux/amba/

Modules: ARM PXA2XX driver
The SDONE and CDONE interrupt on the PXA27x might become unusable in
some conditions. Let's use an hybrid approach (interrupt with timeout)
to have the best possible behavior in all conditions.
Also let's not care about CAR_CAIP anymore. This is useless.

This allows us to eliminate the casts in the drivers, and eventually
remove the use of the device_driver function pointer methods for
platform device drivers.

In PM v1, all devices were called at SUSPEND_DISABLE level. Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.
Since this is obsolete infrastructure which is no longer necessary,
we can remove it. Here's an (untested) patch to do exactly that.

Ensure that sound/arm/Makefile is sanely organised so that additions to it
don't break all other patches out there. This means I only have to adjust
the line numbers in my patch queue rather than having to re-generate by
hand those which touch this file.

ARM PXA2XX driver
This patch extends the period of an AC97 warm reset on the PXA27x from
50uS to 500uS. The shorter reset didn't always guarantee that the codec
would wake up.
Changes:-
o Change pxa27x warm reset period to 500uS
o Removed double semi-colon.

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!
