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
Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>.

6eb5d146d4 ARM: cns3xxx: Use IO memory accessors everywhere
Before it isn't too late let's switch to IO memory accessors.
This patch converts all current _REG users and _REG definitions.
There should be no functional changes.

d94f944e10 ARM: cns3xxx: Add basic support for Cavium Networks CNS3xxx processors
This patch adds very basic support for ECONA CNS3xxx ARM11 MPcore
(ARMv6) dual-core processors.

Note that SMP is not yet supported, as well as many peripheral
devices. Support for these features will be added later.
