The H3 support is still somewhat under development. My H3-based
Banana Pi M2+ had similar sd/mmc issues which I tracked down to a
problem with the lack of pull-ups in the device tree. See the diff
below. You might have to make similar changes to the device tree of
the Orange Pi One to make it work. That requires rebuilding u-boot.
Linux worked because it had a bug and always enabled the pull-ups.
Then they started fixing things and things have become a bit messy. I
think device trees from a the head of the Linux kernel tree do things
differently now and probably won't work with OpenBSD anymore. Not
sure of those new trees have landed in u-boot yet. I any case I
decided to wait a bit for things to stablise in Linux-land.

ARM: dts: sun8i: Enable pull-ups for bananapi-m2-plus SD slot
Board doesn't seem to have external pull-ups and some (but not all) SD cards
don't work without pull-ups.
