>From b053e3239892fa088339db2eb0f33dbaa803f61d Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Tue, 19 May 2009 13:51:45 -0700 Subject: [PATCH] ARM: OMAP4: Create board support for OMAP_4430SDP, v3 This patch creates the bare minimal board files to support OMAP_4430SDP. Additinaly new omap44xx.h is created which contains the base addresses for OMAP4430. File omap34xx.h is adapted to avoid multiple definitions of common omap base address definitions.
