Sorry, I misread your statement above (didn't see the "I'm not asking
about removing console output." part of it.).

I agree 100%. What I would like to have in a new version is that
devices only get initialized before they are actually used in U-Boot,
and get deiniztialized (shut down completely) after being used (not
doing the latter is a continuing PITA in the current code).
