From df1e9d1c218ba696e376cad371b57c0109fe98c9 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 10 Dec 2010 09:46:24 -0800 Subject: [PATCH] omap: Split omap_read/write functions for omap1 and omap2+ Otherwise multi-omap1 support for omap1 won't work as the cpu_class_is_omap1() won't work until the SoC is detected. Note that eventually these will go away, please use ioremap + read/write instead.
