110	help
111	  MPC860 CPUs, prior to Rev C have some bugs in the silicon, which
112	  require workarounds for Linux (and most other OSes to work).  If you
113	  get a BUG() very early in boot, this might fix the problem.  For
114	  more details read the document entitled "MPC860 Family Device Errata
115	  Reference" on Freescale's website.  This option also incurs a
116	  performance hit.
117

123	help
124	  This enables a workaround for erratum CPU15 on MPC8xx chips.
125	  This bug can cause incorrect code execution under certain
126	  circumstances.  This workaround adds some overhead (a TLB miss
127	  every time execution crosses a page boundary), and you may wish
128	  to disable it if you have worked around the bug in the compiler
129	  (by not placing conditional branches or branches to LR or CTR
130	  in the last word of a page, with a target of the last cache
131	  line in the next page), or if you have used some other
132	  workaround.
133
134	  If in doubt, say Y here.
