Actually the sequoia part of the patch bit Markus hard preparing for a
training.  To put the board into a defined state he first erased the
environment, reset the board and did a "run upd".  Seemed a pretty
natural thing to do, but becourse of the erased environment, the tftp
failed and because of the ";" u-boot was erased anyway.

The nasty part he only realized at that moment - although he had U-Boot
still running, tftp would only work with "ethaddr" set _after_ a reset
:(

Oddly enough, a BDI penalty loop reflashing a board reminds me a lot of
biathlon...

Cheers
  Detlev

PS: Yes I know, he could have used serial download or even a USB stick,
    but we only realized that later.
