at91: USB-A9G20 C01 & C11 board support
Add support for Calao USB-A9G20 boards. It will be integrated in existing support for board of same form factor using at91sam9260 or at91sam9263. Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
