Ok.

Done.

Not sure about this one. All at91 boards do it this way, so if a fix
needs to be done, I'd suggest to make it separatly. Is this ok ?

Below is an updated version of the patch. Not sure it's the right way
to resend it, though.

Thanks for the review!

The Calao USB A9263 board is a board manufactured and sold by Calao
Systems <http://www.calao-systems.com>. Its components are very
similar to the AT91SAM9263EK board, so its configuration is based on
the configuration of this board. There are however some differences:
different clocks, no LCD, etc.
