[U-Boot] [PATCH v3] arm: at91: support for the Calao USB-A9263 board (based on AT91SAM9263)

Mon Dec 2 23:30:58 CET 2013
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.
Signed-off-by: Mateusz Kulikowski <mateusz.kulikowski at gmail.com>

Changes for v3
- Updated Makefile to a new build system
- Use generic GPIO for NAND and MAC (requires new GPIO patches)
- Use common at91 phy reset
- Dropped spi0 clock setup (pin is unused)
- Fixed PHY address as 0x0001 and dropped PHY autodetect
(no need for autodetect - PHY address is bootstrapped to 1)
