In that regard this README.zfs is somewhat outdated.  You should set
CMD_ZFS through Kconfig instead.  Which means: pick the matching
defconfig from configs/ subfolder, then run menuconfig and enable
CMD_ZFS, and build that.

Not sure if that Orange Pi 5 Plus is already supported by U-Boot
mainline already.  From a quick glance at the defconfig filenames I
would not know which to pick.

Oh you should have told before.  This uses a custom build script not
part of U-Boot, probably to call U-Boot build.  Please contact that
project on how to change U-Boot config instead.  Or look at their
build.sh and figure out how it configures and builds U-Boot.

Although they seem to use an outdated and patched version v2017.09 of
u-boot: probably not.  Please try with enabling CMD_ZFS in your U-Boot
config first.  It's in the menuconfig, also in v2017.09 already.
