Do you really mean RTC here???

Yes - the 866 and derivatives (859 etc) do NOT have a Real Time Clock
block. This means that hooking the RTC interrupt to 'kick the dog' is
rather difficult :-))

That may be the case. But the watchdog code does not use any  RTC  at
all.

"It is based on the code of Florian Schirmer but using kernel timers (as
used by the DENX driver) rather than the RTC."

Have you ever seen a MPC8xx watchdog driver that used RTC for
triggering?

Gosh - egg on face. Got mixed up with the PIT which usually uses a 32KHz
crystal as does the RTC on the mpc860. Well, we don't have a crystal on
the PIT so that (as well as the non-existant RTC) is not available!!

This is what comes from trying to rely on memory alone with 1358 pages
of mpc866 manual :-))
