From: York Sun Date: Mon, 5 May 2008 15:20:01 +0000 (-0500) Subject: Adding DIU support for Freescale 5121ADS X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=0e1bad47cd345c76c91a64caf41011e431b62599;p=u-boot.git Adding DIU support for Freescale 5121ADS Add DIU and cfb console support to FSL 5121ADS board. Use #define CONFIG_VIDEO in config file to enable fb console.
