arm: mvebu: db-88f6820-gp: Add SDIO/MMC SPL boot support
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:
dd if=u-boot-spl.kwb of=/dev/sdX1
