-Why: We have a boards.cfg file which the vast majority of boards have
- converted over to. Boards that still manually run mkconfig in the
- top level Makefile are either dead, or the maintainer doesn't care,
- or they are doing something weird/wrong that should be fixed in a
- different way, or they need to extend boards.cfg syntax (unlikely).
+Why: We now have a PHY library, which allows everyone to share PHY
+ drivers. All new drivers should use this infrastructure, and
+ all old drivers should get converted to use it.
