 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.
