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

136	  This enables a workaround for erratum CPU15 on MPC8xx chips.
137	  This bug can cause incorrect code execution under certain
138	  circumstances.  This workaround adds some overhead (a TLB miss
139	  every time execution crosses a page boundary), and you may wish
140	  to disable it if you have worked around the bug in the compiler
141	  (by not placing conditional branches or branches to LR or CTR
142	  in the last word of a page, with a target of the last cache
143	  line in the next page), or if you have used some other
144	  workaround.
145
