From fbc9be106e9f27450ea999da74bc24fad04cf41d Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Fri, 14 May 2010 12:05:26 -0700 Subject: [PATCH] omap4: Move SOC specific code from board file This patch moves OMAP4 soc specific code from 4430sdp board file. The change is necessary so that newer board support can be added with minimal changes. This will be also problematic for multi-board, multi-omap builds.
