I agree that the DM configs should be selects where there is no other
option (that will usually, maybe always, be the case with those,
right?).

I can see where the recent changes appear to be a step in the wrong
direction, but I believe they are a step out of an unmanageable local
minima. We simply have to get away from defining configs in arch or
board Kconfigs. Unfortunately, the current mechanism for changing
defaults requires this.

I do not believe that we should do nothing further to improve the way
we use Kconfig, but I do believe strongly that we cannot allow this
approach to defaults to proliferate.

For your specific case, sunxi defconfigs should be no different if you
decide to "select" the DM options that always apply. Perhaps you
didn't look at the next patch which moved all default commands into
the Kconfig where those configs are actually defined?

Cheers,
