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, Wolfram Sang --=20 Dipl.-Ing.
