From f4852ebe6ca946a509667eb68be42026f837be76 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Tue, 20 Feb 2007 09:05:31 +0100 Subject: [PATCH] [PATCH 7_9] Replace ace_readw_ace_writeb functions with macros Register read/write does not need to be wrapped in a full function. The patch replaces them with macros.
