- MPC860 CPUs, prior to Rev C have some bugs in the silicon, which
- require workarounds for Linux (and most other OSes to work). If you
- get a BUG() very early in boot, this might fix the problem. For
- more details read the document entitled "MPC860 Family Device Errata
- Reference" on Motorola's website. This option also incurs a
