It doesn't really matter, the hardware is the same and the DT should
be the same as well, even though U-Boot will not use it to its full
extent. There's even some people using directly the U-Boot DT to boot
Linux. In this case, you wouldn't get all the features supported in
Linux either.

You can sync the H3 DTSI with Linux as well then, we probably didn't
do it for quite some time.

This should have been solved by 341c05865478, which is part of
v2018.05
