with WCR_WDW set, the watchdog won't trigger if we bootet linux and idle around while the watchdog is not triggered. It seems the timer makes progress very slowly if at all. I managed to remain 20minutes alive while the timeout was set to 60secs. It reboots within 60secs if I start a busyloop in userland (something like "while (1) { }").
While I don't see a reason why the WDT should not be running while the CPU is in idle, I'm dropping this bit.

Applied to u-boot-imx, thanks !
Thanks. What just came to mind: In case you do suspend-to-mem. Would the watchdog trigger then? I am not sure and I have no way to test…
