These are three similar files for similar processors, not necessarily
identical copies.

Probably because the 5xx is slightly different than the 8260?

OK, you are right in a way.  In  the  same  way,  the  ethernet  port
configuration  is  board  dependend.  BUt  nevertheless  the ethernet
drivers are specific to  the  ethernet  controllers  as  for  example
provided  by  the MPC8xx or MPC8260 chips, sothe ethernet drivers for
these are in the 8xx resp. 8260 CPU directories.

It is not a coincidence.  The  common  fact  is  that  they  all  use
(processor specific) port pins.

If you have such a patch, please submit it. But please  note  that  I
don't want to add any CPU specific code in the drivers/ directory.
