[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.
