As we have told you before, the help information is picked up
in a weird way due to similar configuration options for the 8260.
The 860T was the first processor with the FEC peripheral block.
If you have an FEC, ask to have it configured, if you don't have
it, don't configure it.

As I have pointed out in a previous message, we don't distinguish
among the 8xx variants in either the configuration or in the
Linux software.  If you have a processor that requires the CPU6
errata workaround, then configure this option, otherwise don't.
It first appeared in silicon prior to 860 Rev. C, but also affected

There is no confusion.  All types of kernel configuration for
nearly any platform will present options that you must be
smart enough to select or to not select depending upon your
board configuration.  Based on the questions you continue
to ask, you are very aware of what you need.  Just configure
your kernel and get on with things.

If you want something different, submit a patch for consideration
that changes the behavior.
