What do you think about this:


video_args_hdmi=setenv video_args $video_args 
video=mxcfb${fbid}:dev=hdmi,1280x720M at 60,if=RGB24\0
video_args_lvds=setenv video_args $video_args 
video=mxcfb${fbid}:dev=ldb,LDB-XGA,if=RGB666\0
video_args_lcd=setenv video_args $video_args 
video=mxcfb${fbid}:dev=lcd,CLAA-WVGA,if=RGB666\0
fb=0\0
video_interfaces=hdmi lvds lcd\0

config_video=for v in ${video_interfaces}; do \
     run video_args_${v}; \
     setexpr fb $fb + 1; \
done\0

mmcargs=setenv bootargs console=${console},${baudrate} \
     root=${mmcroot} \
     ${video_args}\0
...
mmcboot=echo Booting from mmc ...; \
     run config_video; \
     run mmcargs; \
     ...


Now video interfaces can be selected and reordered at will just by 
editing video_interfaces env-var.
