That looks like another deviation from the Linux DTs, right?
Yesterdays I tried to update U-Boot with the Linux DTs, but this gets
nasty because of the entanglement with the H3 and the non-upstream
Ethernet support.
Following the new scheme we would need to have a ...-u-boot.dtsi with
the Ethernet nodes for *each* board, as some H3 boards use 100Mbit, some
have a Gbit PHY, so we can't use a single file to cover both.

Not sure if that means we use two .dtsi files and symbolic links or
whether we want to wait until we can have multiple, possibly shared
-u-boot.dtsi files to tackle this.

Cheers,
Andre.
