Add cfb console support to FSL 8610 DIU driver. Inspect board version from PIXIS to obtain correct pixel format. Use #define CONFIG_VIDEO in config file to enable fb console. To switch monitor, set monitor variable to 0 - DVI, 1 - Single link LVDS, 2 - Double link LVDS followed by "diufb init". Preserve logo bitmap at the top of the fb console.
