[U-Boot] [PATCH] imx51:Add support basic boot code of freescale imx51 bbg board

Sun Sep 20 19:28:21 CEST 2009
From: Fred Fan <fanyefeng at gmail.com>
This patch just supports boot into u-boot from mmc or spi-nor flash.
It just implements console, iomux and clock. There are no ethernet,
nor-flash, mmc or other peripheral drivers.
