I tried to build an actual u-boot from git for my odroid-c2 board.
Which git repository did you use?
If you can enable CONFIG_MMC_TRACE, it's more helpful to debug.

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:
