Hmm..., actually this is the respect for you guys. But yes, my intention is AMD take over the maintainership over Platform\AMD, but still leave the maintainership to you and Ard for OverdirveBoard 😊. But we can help on it if you encounter some problems.
Or you would like AMD to take over everything? We are not familiar with OverdriveBaord though.

Abner
