>From f48199dc44e1bf5f56aa981d20f35dc8ce1113bf Mon Sep 17 00:00:00 2001 From: Vimal Singh <vimalsingh@xxxxxx> Date: Tue, 1 Dec 2009 11:24:46 +0530 Subject: [PATCH] OMAP3: Add support for flash on 3430SDP board This patch adds support for flashes on 3430SDP boards. All three NAND, NOR and OneNAND are supported. I have tested it on 3430SDP (ES2 and ES3.1). This patch can be treated as an example to "how to utilize": 'gpmc-nand.c' and 'board-sdp-flash.c'. Similar patches can be created for 2430sdp and 3630sdp or any other similar board.
