From 8449f287f5c53d59db13c3c512e6bd1750b692d1 Mon Sep 17 00:00:00 2001 From: Magnus Lilja Date: Wed, 1 Jul 2009 01:07:55 +0200 Subject: MX31: Add basic support for Freescale i.MX31 PDK board. Add support for Freescale's i.MX31 PDK board (a.k.a. 3 stack board). This patch assumes that some other program performs the actual NAND boot.
