I'm not sure I know anyone that still has a mpc5121. Maybe someone on 
linuxppc-dev?

I did try to take the patch for a spin on my T2081RDB but I'm having 
some userland issues on it for some reason (unrelated to this change). 
The kernel boot does discover a few peripherals hanging of the I2C 
interface but I'm not in a position to offer up a Tested-by and I've run 
out of time to debug why my board is unhappy.
