That shgould be no problem. We have a couple of boards that have watchdogs enabled, some with really strict requirements (like triggering the watchdow every 80 milliseconds). > I tried to define macros like CONFIG_HW_WATCHDOG / CONFIG_WATCHDOG, but I'm > not > happy for the result.

I can't speak for MIPS in general, but the common infeastructure should work just fine. > I don't understand if u-boot supports or not watchdogs in a "structural" > manner.

It's a standard feature being used actively on several boards, some of them in mass production.
