 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.

 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.
