Actions is not yet supported in mainline U-Boot, and S500 boards did not
have a problem there. The saveenv command is simply not enabled in this
config deployed by Cubietech. Since I have not succeeded in getting a
self-built U-Boot booted from SD, I cannot test individual commits on
top either.

Maybe Cubietech or Actions can comment?
