Subject: [PATCH 3/3] sunxi:Added difference MMC SLOT for booting
Signed-off-by: Zhi Yuan Wan <dv...@qq.com>
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
