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

+The location of the vectors file object is critical.
+
+From the comments at the head of vectors.S:
+
+  The issue with this file is getting it loaded at the right place.
+  The first vector MUST be at address 0x????0100.
+  How this is achieved is dependant on the tool chain.
+
+...
+
+  The variable 'PPC_VECTOR_FILE_BASE' must be defined to be the
+  offset from 0x????0000 to the first location in the file.  This
+  will be either 0x0000 or 0xfff0.
+
+The eth_comm BSP defines PPC_VECTOR_FILE_BASE to be 0x00000000.
+The MBX8xx BSP also defines PPC_VECTOR_FILE_BASE to be 0x00000000.
+Change these values to 0xFFF00000 if your are implementing an actual
+boot rom.
