Something is wrong there.
You should try to apply this "revert" that was committed in linux.
Hope
they'll soon make up their minds and commit a newer version.
The device tree that is included with
/usr/local/share/u-boot/orangepi_one/u-boot-sunxi-with-spl.bin
should still have emac nodes.
But they use a different binding from the Linux kernel, which are the
ones Patrick
used for the implementation. And some of the regulator stuff is missing
so things don't actually work even if we would change the driver to use
the
bindings currently used by U-Boot. It's a mess.
So using the dtb from Linux with the revert applied is the way to go for
now.
