OK, so in fact you are not just renaming the board file, you are using
the previous board EVM DTS to describe a completely different board.
You are recycling the old non supported EVM.

You should update the subject and changelog to reflect that, because
that's rather confusing.

You should explain why. I don't think this is obvious for people outside TI.
