watchdog in lite5200

i am tring to use the watchdog in a lite5200
In menuconfig , i find the watchdog in char devices
but none of the cotrolers is for internal watchdog of mpc5200
In 5xxx/IO dont appear to show a driver for internal watchdog either.

So i have to develop the driver for watchdog in mpc5200 ?
thanks
