The hardware is compliant with WDRT specification, so I originally considered including generic WDRT watchdog support, but decided against it, because I couldn't find anyone to the code for me. WDRT seems to be not very popular. Besides, generic WDRT porbably requires a slightly different driver approach. Reviewed by: des, gavin, rpaulo MFC after: 3 weeks
