[BUG] U-boot does not detect emmc card in odroid-c2 for newer U-boot as 2020.04

[Otto Meier]

I tried to build  an actual u-boot from git for my odroid-c2 board.

It doesn't find the emmc card and therefore does not boot from it.
emmc is Ok and boots with u-boot 2020.04 fine.

Newer u-boot then 2020.04 show these messages:
