Add support for Bluewater Systems Snapper9260/9G20 modules. The
modules are based on the AT91SAM9260 and AT91SAM9G20 processors
respectively and support NAND flash and Ethernet.

It would be better if you based it on the reworked at91 code at git://git.denx.de/u-boot-atmel.git rework101229 branch. For templates see the at91sam9260ek port there.
