Hi Simon,
With the EOL of python2 soon I've been looking at the Fedora U-Boot builds to see what it would take to move over to python3. There's a couple of issues building the bundled pylibfdt, the first is the Makefile hard codes python2, the second is that the generated libfdt_wrap.c doesn't seem to find the python3 version of Python.h (errors below).
It seems upstream now supports building pylibfdt with dtc 1.5.0 but I couldn't quite work out how this fits into the U-Boot bundled version. Is there plans to be able to support pylibfdt with python3?
Regards, Peter
