Subject: arm: mvebu: Add SPL SDIO/MMC boot support
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=8ed43b966ccf7f1153f553dce86de60a6e0e9d9a;p=u-boot.git

arm: mvebu: Add SPL SDIO/MMC boot support

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.
