I'd like to start some more general discussion here.

All the sunxi boards don't have a PMIC to do the reset properly, so we
chose to do the reboot hook using the watchdog.

How is that handled usually? Obviously, we could have a rather minimal
approach, like this one, where we have code duplication between the arch
code and the watchdog driver code, which is probably not so nice, but I
couldn't find either any convention for this, or a piece of
infrastructure to do so.

What could be the preferred solution?

Thanks,
Maxime
