[RFC, PATCH 1/3] arm: return both physical and virtual addresses from addruart
Jeremy Kerr

Tue Jul 13 22:09:37 EDT 2010
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.
