Suggestions for BSPs to Obsolete

[Joel Sherrill]

Hi

I am looking for suggestions on BSPs to remove. If you
have used a BSP in the past but no longer use it, please
speak up. BSPs with no users are baggage to the project.

If you have suggestions for other reasons, please speak up
as well. EOLed boards that no one can have, custom
variants that are no longer in use, etc.

Help reduce the maintenance!

Thanks.
