Are you looking for the old "ppc405 watchdog" driver that simply
hooked into the generic PPC heartbeat facility? Or are you looking
for a driver that utilizes the 4xx/booke hardware watchdog facility?

I am looking for a driver that utilizes the 4xx/booke hardware watchdog 
facility.

FYI, I wrote a driver uses 4xx/booke hardware watchdog.
BTW, is hooking PPC heartbeat facility obsoleted?

I see.  The ppc_md.heartbeat facility isn't going anywhere as there
are multiple users.  It's possible to take the "ppc405_wdt" driver
with a rename and minor cleanup have it be a generic timebase driven
watchdog driver that is compliant with the familiar WD interface.

What do you see as the advantage to having a watchdog driver
that uses the booke hardware watchdog facility over a generic
timebase driven driver?
