There are many bad examples. In general (and excluding shoving stuff under board/.../Kconfig) I prefer those values to be in the top-level Kconfig that asks them rather than per-arch so that it's (a) hopefully clear that yes, SoCs can and should add a default when it's known and (b) because perhaps this will lead to someone thinking on the problem of how ugly it can be and what may be a better solution. Kconfig is certainly better than CML1 was/is, and better than our ad-hoc just define stuff in board.h files, but it's not perfect. OTOH, if someone wants to break down the options we've put (I've told people to put) in the top-level Kconfig and instead demonstrate and document a reasonable places to put them, OK. And if you really want to say that this should just match mx7 for today and move on for now, alright. -- Tom
