[U-Boot] CONFIG_WATCHDOG on MPC85XX and QorIQ P1/P2

Hi,

I'm trying to enable watchdog in u-boot on P1011 based platform. I've noticed that all 85XX platforms have CONFIG_WATCHDOG disabled. There's a definition of reset_85xx_watchdog() in cpu/mpc85xx/cpu.c but no code that actually enables the watchdog.

What should be done to make this feature working on these platforms ?

Thanks a lot.

Felix.
