6075e9df47 ARM: 6949/2: mach-u300: fix compilaton warning in IO accessors
The IO accessors for U300 were using u32 rather than the nominal
void __iomem * type, rectify this by properly defining the
virtual base for statically mapped peripherals to be
void __iomem *. Requires fixing a field in struct clk as well.

0ea1293009 arm: return both physical and virtual addresses from addruart
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.

Updated with fixes for OMAP from Jason Wang <jason77.wang@gmail.com>
and Tony Lindgren <tony@atomide.com>, and fix for versatile express from

1dbd30e989 ARM: 6225/1: make TCM allocation static and common for all archs
This changes the TCM handling so that a fixed area is reserved at
0xfffe0000-0xfffeffff for TCM. This areas is used by XScale but
XScale does not have TCM so the mechanisms are mutually exclusive.

This change is needed to make TCM detection more dynamic while
still being able to compile code into it, and is a must for the
unified ARM goals: the current TCM allocation at different places
in memory for each machine would be a nightmare if you want to
compile a single image for more than one machine with TCM so it
has to be nailed down in one place.
