* i.e. its RST pin is connected to the WDR input of the CPUs or
* something. The `eeprom' nodes of E250, E450 and the clock board
* variant in Exx00 have such properties. For E250 and E450 the
* watchdog just works, for Exx00 the delivery of the reset signal
* apparently has to be additionally enabled elsewhere...
* The OFW environment variable `watchdog-reboot?' is ignored for
