This patch adds support for our companies board CDU9G25 with Atmel AT91SAM9G25, 128MB DDR2, 256MB NAND.
Signed-off-by: Jiri Prchal jiri.prchal@aksignal.cz --- v2 Fixed static IP and MAC addr cofiguration by random MAC and DHCP. Added entry to MAINTAINERS. Fixed line lenght, trailing spaces and other cosmetics. v3 Removed static eth_gadget addresses. MAC address set from serial number of F-RAM. Kept CONFIG_SERVERIP as default configuration.
