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

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