The selection takes place immediately, so if you have a panel connected,
you should see valid output on the display.
Note that if you change resolutions, the display memory will likely have
mis-aligned data in it. Displaying a bitmap on the display through the use
of the fatload and bmp com mands will remedy this situation. Refer to
init.script for an example.
If you want to make your s elec tion s tick through a reset, you can save it
through the set and save U-Boot commands.
