These pins are multiplexed between ARM boot mode and the VPBE. At
reset, the boot mode inputs BTSEL0 and BTSEL1 are sampled to
determine the ARM boot configuration. See below for the boot modes set
by these inputs. See the Bootmode section for more details.
After reset, these are video encoder outputs COUT0 and COUT1, or
RGB666/888 Blue output data bits 3 and 4 B3/B4.
