always, but not necessary to turn a board on if it's already configured.

How would kernel know if it's already configured, correctly?

What would happen if a board were designed that only used the default ALT
settings on i.MX53 or so? You'd have to redefine every default IOMUX pad
just to get it to boot. That's intolerable.

Come on, even the pad configuration are all the default?  Even if that's
the case, yes, we still need to do it.  How do we know if firmware has
changed the settings or not.
