You always have to know the interface to the U-Boot build framework,
there is no way around that.

Well, you must know that the U-Boot build framework does support these
options (or whatever they might be called), assuming they existed.

Well, that's the default for many board configurations - at least for
all where I have something to say about the implementation.

It's in your hands to make it the default for all your boards, too.

I'm not sure if this is the right approch. To me it seems that a small
wrapper script, optimized for your (or my) purpose, is much more
flexible and does not pollute the Makefile for features only very
few people ever need.
