From a02eb8da02741f43efb6f06adf534f9f2b913d80 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Tue, 28 Aug 2007 00:28:09 +0900 Subject: [MIPS] tx4927: Cleanup unused macros and non-standard IO accessors. This patch removes many unused constants, replaces non-standard IO accessors with standard ones, and kills terrible tx4927_mips.h file.
