121	help
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.
128
129	  If in doubt, say N here.

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