From 46ea178b7a5162405bf70954d769165cf2161309 Mon Sep 17 00:00:00 2001 From: Hirokazu Takata Date: Fri, 6 Jan 2006 00:18:43 -0800 Subject: [PATCH] [PATCH] m32r: Update _port2addr to use NONCACHE_OFFSET Modify _port2addr*() routines in arch/m32r/kernel/io_*.c to use NONCACHE_OFFSET instead of hard-coding of a constant address. This modification is also required to support an M3A-ZA36 FPGA eva board in case an MMU-less synthesizable m32r core is used.
