This patch adds basic SDIO/MMC booting support to MVEBU SoC's. Since I don't know of a way to test the boot-device upon runtime, this patch hardcodes the spl_boot_device instead. Tested on Marvell DB-88F6820-GP board. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr> Cc: Dirk Eibach <eibach@gdsys.de>
