Hi Stefan,

This patch adds the configuration options to boot via SDIO/MMC on the Marvell DB-88F6820-GP Armada A38x board. The default boot device is still SPI NOR flash.
To enable MMC booting on this board 2 things need to be changes: a) Change kwbimage.cfg BOOT_FROM sdio b) In the config header select #define CONFIG_SPL_BOOT_DEVICE SPL_BOOT_SDIO_MMC_CARD
The generated image needs to be copied to the first bootable MMC partition:
Can you please define "bootable" here? Does the partition really need to have bootable flag configured?
Thanks, Luka
