Patch from John Cotton <john.cotton@nrc.ca>, Charles-Antoine Gauthier

<charles.gauthier@iit.nrc.ca>, and Darlene A. Stewart
<Darlene.Stewart@nrc.ca> to add support for a number of very
significant things:

  + BSPs for many variations on the Motorola MBX8xx board series
  + Cache Manager including initial support for m68040
    and PowerPC
  + Rework of mpc8xx libcpu code so all mpc8xx CPUs now use
    same code base.
  + Rework of eth_comm BSP to utiltize above.

John reports this works on the 821 and 860

+ *  _Objects_Local_iterate
+ *
+ *  DESCRIPTION:
+ *
+ *  This function invokes the callback function for each existing object
+ *  of the type specified by the information block pointer. Iteration
+ *  continues until either all objects have been processed, or, if
+ *  break_on_error is TRUE, until an invocation of the callback returns
+ *  something other than 0.
+ *
+ *  Input parameters:
+ *    information:
+ *      A pointer to an Objects_Information block. Determines the type of
+ *      object over which to iterate.
+ *    callback:
+ *      A pointer to a function with the indicated signature.
+ *    arg: 
+ *      A pointer to some arbitrary entity. Passed on to the callback.
+ *    break_on_error
+ *      If TRUE, stop iterating on error.
+ *
+ *  Output parameters: NONE
+ *    But callback may write into space pointed to by arg.
+ *
+ *  Return value:
+ *    0 if successful
+ *    Value returned by the callback otherwise.
