Add support for USB-A9263 board manufactured by Calao Systems
(http://www.calao-systems.com/).
Code is based on old U-Boot sources (2010.09) released by Calao and
existing AT92SAM9263-EK code.

Heiko proposed a solution for unifying macb reset sequence.
@Heiko will you send another patch?
I thought I wait for your GPIO update patches, and rebase my patch-
serie for the siemens boards on them ...
Ok, based on the spl patches from bo shen, see
http://lists.denx.de/pipermail/u-boot/2013-November/166272.html
I can sent soon the "phy_reset" patch, if the patch passes a
"MAKEALL" ;-)
bye,
Heiko
