[U-Boot] [bug report] sunxi: booting from eMMC

On marsboard today i used 2014 u-boot, sd card on sdc0 hardware lines and emmc on sdc2 hardware lines.
and get error "Card did not respond to voltage select!» , then i tried to boot without sd card, only with emmc on sdc2

On my board i used mainline u-boot, emmc on sdc0 hardware lines.
And get block read error, logs below.

Brom on A20 chip firstly tries sdc0, if fail, then sdc2.

I dont checked only gpio pins, maybe in det pin problem, i will try, thx.
