Is petting of watchdog supported in MPC827x?

[NM]

Hi,
   Is there any framework in place to support petting of a watchdog (in our case external) on MPC8271 powerpc platform?

Having searched around in the tree, I only see support for MPC8313 soc, but not for 8271.

Any pointers would be appreciated in order to avoid duplication of effort.

thanks
