Some platforms (like OMAP not to name it) are doing rather complicated
hacks just to determine the base UART address to use.  Let's give their
addruart macro some slack by providing an extra work register which will
allow for much needed cleanups.

This is basically a no-op as this commit is only adding the extra argument
to the macro but no one is using it yet.

Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.

This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.

Adds core support for the ST-Ericsson U8500
platform. It supports memory mappings, binds to
the existing modules like GIC, SCU, TWD and
local timers and sets up the infrastructure for
the secondary core.

Patch from Vitaly Wool

This patch adds kernel headers for PNX4008 ARM platform.
It's basically the same as the previos one, but with the rmk's comments taken into account.

Since we now only build arch/arm/kernel/dma.c on machine types
which set ISA_DMA_API, we don't need to define MAX_DMA_CHANNELS
to 0 to indicate this - this definition becomes superfluous.
Remove it.

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!
