+* Enable address translation on MPC83xx
+  Patch by Kumar Gala, 10 Feb 2006
+
+* Decopuled setting of OR/BR and LBLAWBAR/LBLAWAR on MPC83xx
+  Patch by Kumar Gala, 25 Jan 2006
+
+* Fixed defines for MPC83xx SICRL register to match current specs
+  Patch by Kumar Gala, 23 Jan 2006
+
+* Only disable the MPC83xx watchdog if its enabled out of reset.
+  If its disabled out of reset SW can later enable it if so desired
+  Patch by Kumar Gala, 11 Jan 2006
+
+* Allow config of GPIO direction & data registers at boot on 83xx
+  Patch by Kumar Gala, 11 Jan 2006

+* Enable time handling on 83xx
+  Patch by Kumar Gala, 11 Jan 2006
+
+* Make System IO Config Registers board configurable on MPC83xx
+  Patch by Kumar Gala, 11 Jan 2006

   If a BAR is prefetchable and no prefetchable region has
   been setup by the controller we fall back to allocating
   the BAR into the normally memory region.
