/* TODO: the YP-CP3's power-hold line is not known yet. The rk27xx generic
* board holds power on PC0; driving a pin whose job on this board is unknown
* could do anything, so nothing is touched. Whatever the boot ROM or the
* original firmware left holding power stays holding it, and power_off()
* cannot switch the player off. */
