[PATCH] ARM: 2745/1: Fix IXP4xx debug macros
Patch from Deepak Saxena
Current IXP4xx debug macros do not work in the small window between
the MMU being enabled and the call to map_io() b/c the standard
peripheral mapping is not properly setup for use with the low-level
debug code. This patch creates a new section-aligned mapping for the
UART specifically for use with the debug macros.
