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

140	help
141	  This enables a workaround for erratum CPU15 on MPC8xx chips.
142	  This bug can cause incorrect code execution under certain
143	  circumstances.  This workaround adds some overhead (a TLB miss
144	  every time execution crosses a page boundary), and you may wish
145	  to disable it if you have worked around the bug in the compiler
146	  (by not placing conditional branches or branches to LR or CTR
147	  in the last word of a page, with a target of the last cache
148	  line in the next page), or if you have used some other
149	  workaround.
150
151	  If in doubt, say Y here.
