I submitted a patch to enable pipelining on a MPC5200B recently. It was
disabled because of a bug in the MPC5200. The first version of this
patch used MPC5200_BUGFIX and it was mentioned, that some people might
want to run the same kernel on both kind of processors. So, the patch
that went mainline checks for the PVR. Maybe we should stick to this
here, too?

All the best,
