This patch adds board support for ATNGW100 mkII. This board is an upgrade of the ATNGW100 where the difference is an additional 256 MB NAND flash device and 128 MB 32-bit SDRAM instead of the 32 MB 16-bit SDRAM on ATNGW100. Tested on ATNGW100 mkII, duh (-: Signed-off-by: Hans-Christian Egtvedt <hans-christian.egtvedt@atmel.com> Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
