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.

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.
