Great! Also you could look at my series here:

The device tree method is not good, I think we need a tool that chops the device tree down automatically for SPL. But otherwise, the support is there for device tree in SPL.
Amazing! It is very nice that OF_CONTROL can be available with such small memory footprint.
I can use 64KB for SPL on my boards, so it will surely work for me. I will check it out!
Thanks for your hard work all the time!
Thanks! Yes it has worked out well. It is still overhead but it is tolerable overhead for most modern platforms, I think.
I look forward to hearing what you find.
Re the tool, I think we need something like:
fdtsubset -a serial0 -a /gpio <in.dtb> <out.dtb>
which looks up the alias 'serial0' and the /gpio node and creates a device tree subset containing just enough to allow that to work. I did a more general-purpose 'fdtgrep' tool along those lines a long time ago but it was not accepted to dtc.
