Hardware watchdog?

[pushbx]

Is there a hardware watchdog that could be enabled by U-Boot?  I find that I could hang the sheeva plug with a bad kernel image or filesystem.  A hardware watchdog would be a great help if you do remote development.

As far as I know you should have something like /dev/watchdog if you have a hardware watchdog. The plug seems not to have one but maybe someone knows how to enable one if present.
