From 5932ae3f5d610fd8d047ef4693bab9f084e5c56d Mon Sep 17 00:00:00 2001 From: Deepak Saxena Date: Fri, 24 Jun 2005 20:54:35 +0100 Subject: [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.
