Since 2014-08-01 the SD/MMC for Kirkwood has been rewrote and mainlined. It's now drivers/mmc/mvebu_mmc.c and the older MVSDIO (drivers/mmc/mvsio.c) and MRVL_MMC were removed. http://git.denx.de/?p=u-boot.git;a=history;f=drivers/mmc/mvebu_mmc.c;h=8ca09042d8d9280c94b9f5620b8e8a10ae8862a8;hb=HEAD All issues with SD/MMC on Kirkwood platforms need refresh and might be closed.
