This hierarchy contains support routines for some of
the varied and quite numerous PowerPC processors
available from IBM and Motorola.

Since these routines can differ amongst different members
of the PowerPC family, an entry per CPU type is provided.

At this time, support is included for the following PowerPC
family members using the new exception processing model:

  + mpc505
  + mpc6xx
  + mpc750
  + mpc821 
  + mpc823 (uses mpc821 directory)
  + mpc850 (uses mpc860 directory)
  + mpc860
  + mpc8260

The following PowerPC family members are supported but
still use the old exception processing model:

  + ppc403
  + ppc405 (uses ppc403 directory)
  + ppc6xx (no libcpu support)

Note that because of similarities in various family members,
the mpc823 should be able to use the mpc821 code and the
mpc850 should be able to use the mpc850 code.
