From 52c543f90c4095dff71dc125017594b61a753069 Mon Sep 17 00:00:00 2001 From: Quinn Jensen Date: Mon, 9 Jul 2007 22:06:53 +0100 Subject: [ARM] 4461/1: MXC platform and i.MX31ADS core support This patch adds the foundation pieces for the Freescale MXC platforms, including i.MX2 and i.MX3 based systems. The bare-bones MX31 support in this patch boots to the rootdev panic with 8250 serial console configured "console=ttyS0,115200". It assumes that Redboot is the boot loader.
