Esto es un volcado de printenv para tener bootargs que arrancan desde mmc o bien desde nand de manera automática.

Algunas otras resoluciones de pantalla posibles son (sacadas de aqui):

• omapfb.mode=dvi:1024x768MR-16@60
• omapfb.mode=dvi:1280x720MR-16@60 (for 720p HDTV with 1:1 pixel mapping)
• omapfb.mode=dvi:1280x1024MR-16@60 (tested on revB7, actual output is 57MHZ and may not work on some devices)
• omapfb.mode=dvi:1360x768MR-16@60 (works nice on 720p HDMI TV which crops edges due to overscan)
