some Blackfin boards support CONFIG_VIDEO so there is a splash screen while u- boot is running. however, we dont always boot a Linux image with a video driver enabled. so sometimes a few weird things can occur due to the DMA always running in the background (such as attempting to suspend to RAM).
there doesnt seem to be any support with CONFIG_VIDEO though for turning
things off. i can also see cases though where people wouldnt want to turn the
video off until the OS is up and running and ready to take over the display
("flicker free" and what not). but on our Blackfin development boards, we
arent concerned with that by default.
so should i extend the CONFIG_VIDEO interface to include an option to shut
down the video before booting an OS ? similar to the call to usb_stop() in
cmd_bootm.c.
