  50           used without any software interaction over the MDIO interface, so
  51           all MII code can be omitted. Say N here if unsure or if you don't

  97           MPC860 CPUs, prior to Rev C have some bugs in the silicon, which
  98           require workarounds for Linux (and most other OSes to work).  If you
  99           get a BUG() very early in boot, this might fix the problem.  For
 100           more details read the document entitled "MPC860 Family Device Errata
 101           Reference" on Motorola's website.  This option also incurs a
 102           performance hit.
 103
 104           If in doubt, say N here.
