Not yet, here is the comment in hal_cache.h // FIXME: // The revision A.2 MPC860 might do all sorts of horrible things to // the cache contents in a few specific (and unlikely) // situations. However, as I don't feel like being bitten by these, // leave caches disabled at all times. Also, the MMU needs to be enabled for the cache's to work and I don't see code for that. It's going to be board dependent anyway. Also, once you enable the cache there are additional issues with dealing with the CPM to do I/O. -- Stuart
