I always thought the name "examples" was clear enough. This is NOT a
place for general purpose code, especially not for borad-dependent

Why a new scheme instead of simply using what's already in place and
being used by others?

No. "examples" means example code, and to be more specific: examples
for standalone programs. Board dependent code belongs to board

If you really feel you must create a sub-directory in your board
directories feel free to do this. To me it makes little sense,

For example, have a look at the board/trab directory; the Makefile
there includes rules to build a custom tool "trab_fkt" which is used
by the board manufacturer for burn-in tests. This is totally transpa-
rent to the rest of the U-Boot tree.
Feel free to do something similar. I see no real need for a new level
