From 68cb700c59fae6cd539c9dc1e9f2584f671935a0 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 31 Aug 2012 17:04:35 -0700 Subject: ARM: OMAP1: Move SoC specific headers from plat to mach for omap1 There's no need to have these in plat-omap any longer. Note that these could eventually be made local to mach-omap1 instead of being in mach. But to do that, at least various driver access using omap7xxx.h registers needs to be fixed first.
