From 941132606c7611246d2034cb7b01f9270c2d1ede Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 28 Aug 2009 10:50:33 -0700 Subject: OMAP: Remove OMAP_IO_ADDRESS, use OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS instead Search and replace OMAP_IO_ADDRESS with OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS, and convert omap_read/write into a functions instead of a macros. Also rename OMAP_MPUIO_VBASE to OMAP1_MPUIO_VBASE. In the long run, most code should use ioremap + __raw_read/write instead.
