Well such per-board driver would handle the board-specific init, like
configuring the hub GPIO (as Richard has to do so on mx6q) or flick some other
GPIOs, configure registers etc.
You can not depend on a bootloader to do such init for you, even though the
bootloader should do it and should do it right.
