I'm definitely not an authority on this, but I think not. From a quick scan
the strategy is to disable the wdt if it's going to be a problem. There
seems to be some API to trigger a reset via the wdt, but that's all.
Platform may be an issue because the platform may not implement those
functions.
(Note I didn't look very hard - I invite anyone to correct me).
Cheers
Marc
