This is really concerning since it's jumping straight to open coding the algorithm in platform specific code which isn't great, especially since that platform specific code is now going to have to handle all possible board specific restrictions that might be found on that platform. Why is it not possible to express the rules that exist in a more general fashion which can be encoded in drivers? I'm not thrilled about later patches that export core functionality for platform specific use either.
