Add support for Eukrea CPU9260/CPU9G20 SBC
these boards are built around Atmel's AT91SAM9260/9G20 and have up to 64MB of NOR flash, up to 128MB of SDRAM, up to 2GB of NAND and include a 10/100 Ethernet PHY in RMII mode. Signed-off-by: Eric Benard <eric@eukrea.com> Signed-off-by: Tom Rix <Tom.Rix@windriver.com>
