Subject: [PATCH 3/3] sunxi:Added difference MMC SLOT for booting

Signed-off-by Zhi Yuan Wan <[email protected]>

There is a much simpler / easier way to do this, simply add a:

CONFIG_MMC_SUNXI_SLOT_EXTRA=2

Line to the defconfig, then an u-boot will be build which supports booting from both the external sdcard slot as well as from the emmc, and it will figure out where it is booting from and use that as bootdevice itself.

Regards,

Hans
