Sorry, let me try and be clearer.  Which hardware platforms did you test
this on?  There's quite a lot of Allwinner SoCs, and it's not clear at
all if Paul's problem is because of something on the SoC on the Bananapi
M2 Ultra (because it's not clear if another platform with that same SoC
was tested) or how the board is wired (DM MMC is fine on that SoC, but
was tested on something where uSD/MMC are opposite of that platform or
...).
