ACK. Had the linker approach also in mind, but didn't want to touch each
and every lds. But definitively the more elegant solution.

Sigh. Big brown paper bag for me.

Solves exactly the "issue" I described and works perfectly. And is
documented very well in the README. As usual, things are already solved
in U-Boot. Thanks for the pointer.

Really had blinkers on, no idea why I didn't see it. Respectively, saw
it but somehow mixed it up with hardcoded, read-only environment.
Lession learned: Get some sleep before scribbling senseless RFCs.

Sorry for the noise, case closed.
