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