I'm fine with this.

Hmmm. I prefer to add this "u-boot,dm-pre-reloc" to the board dts
file instead of using the dtsi files. At least for the real devices,
like UART etc. As they vary between the different boards.

Perhaps its possible to enable those busses (simple-bus) needed
to traverse to the requested device automatically via fdtgrep?
That would make this much easier and less error-prone. And would
result in less "u-boot,dm-pre-reloc" occurances in the dts / dtsi
files.

Thanks,
Stefan
