Well, yes, I added this trivial wrapper. I can (and probably will) post
it to Linux, but actually it would be sufficient to have some DT in
U-Boot (and on the SPI flash!), so that one can just use $fdtcontroladdr
and be done.

In case you wonder about (other) differences between mainline and this
series: There is this one path name change in the sun50i-h5.dtsi,
mentioned in the 3/7 commit message, plus I left in the common libretech
.dtsi Chen-Yu created for U-Boot. I guess we will see this sooner or
later in Linux and can then sync this back, if needed.

Cheers,
Andre.

Are these based purely on 4.17rc5 because I don't see
sun50i-a64-pine64-lts.dts in Linus's upstream.
