From 030b15457d8069a6255579a28db196e002cb9c86 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 3 Jul 2008 12:24:41 +0300 Subject: ARM: OMAP: Change omap_cf.c and omap_nor.c to use omap_readw/writew instead of __REG Change omap_cf.c and omap_nor.c to use omap_readw/writew instead of __REG. This is needed for multi-omap in the future.
