Though Freescales doc for MPC83xx says:

• Functional and programming compatibility with MPC8260 watchdog timer

further reading shows that there is a "little" difference. MPC83xx can
come out of reset with WDT disabled, while MPC82xx can't. So the approach
for MPC83xx is not possible on those other systems.

So, any other idea? Is the WDT on MPC8248 usable at all?
