Daniel started cleaning up the FDT implementation in crosvm recently:
https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/2713569
That might be a good starting point. It still has some work to do IIRC. If
it looks useful, we can move it to a separate crate as it's currently in
that aarch64 code.
