I was just discussing this with Wolfgang again and actually you should use CONFIG_WATCHDOG for this. The latter was meant for CPU internal watchdog functionality, whereas CONFIG_HW_WATCHDOG was for external (i.e. i2c or other) separate watchdog chips. I'm working on a patch to README to make this more widely known.

Why cannot we put the code into i.mx31 specific code and only keep the config board specific? In this patch there is (again) zero board dependency, so all i.MX31 boards should be able to profit from the work.
Thanks Detlev
