Dear Shawn Guo,

Apart from my comments below, we really need to know Rob and Grant's
opinion on this.

Hm ... so why don't you actually write per-board driver ? :-) That'd
handle every single board very well, you'd configure the GPIOs there,
every single additional necessary thing that has to be configured would
sink there too etc.

I'm not completely sure about how the per-board driver looks like
exactly.  Can you have some code demonstrating it?

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.

Shawn
