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?
