Add support for the ARM part of the mgcoge2, named suen3. This board is based on the Marvell Kirkwood (88F6281) SoC. As there come more board variants, common config options are collected in include/configs/km_arm.h. Also, this board use common code for all keymile boards, which is stored in board/keymile/common/common.c Signed-off-by: Holger Brunck <holger.brunck@keymile.com> Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Heiko Schocher <hs@denx.de>
