Correct. It works fine in linux. I've even tried to port linux code that
enables watchdog (booke_wdt.c/__booke_wdt_enable()) to u-boot,
but was not successful. Watchdog never triggered, although I did
not refresh it.
I'd appreciate some advice on what may be different in u-boot
vs. linux.
Thanks a lot.
Felix.
