I have tested this on the AM62Px SK EVM. I did *not* apply the
dependency (20241217204835.3312765-1-j-humphreys at ti.com) and it worked
fine for me:

I did:
$ snagrecover -s am625 -f ./am62px-sk-evm.yaml

Boot logs:
https://paste.debian.net/1340393/

Also tested that I could enumerate the board with "fastboot".
