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
