From: Tony Lindgren Date: Fri, 10 Dec 2010 17:46:24 +0000 (-0800) Subject: omap: Split omap_read/write functions for omap1 and omap2+ X-Git-Tag: 2.1b_release~5940^2~50 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=df1e9d1c218ba696e376cad371b57c0109fe98c9;p=platform%2Fkernel%2Fkernel-mfld-blackbay.git 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.
