Sascha, thank you for the prompt response.
Unfortunately the new version works only partially with my Beagle
Board (rev. C4).

I tested commit:
 46976f7 OMAP: fix compilation

- Test 1: the board is always powered.
  Press RESET with the USER key pressed.
  10 tests, 10 passed.

- Test 2: the board is not powered.
  Turn turn it on with the USER key pressed.
  Turn turn it off again at the end of the test.
  10 tests, 5 passed, 5 failed.

During all of the 20 tests, barebox.bin was always the same.
I didn't recompile it.

OTOH the commit before the "reimplement in C" passes also test 2.

I hope this gives enough hints to solve the problem.

Luca
