Changes since U-Boot 1.1.4:
======================================================================
* 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
* Fixed PCI indirect config ops to handle multiple PCI controllers
We need to adjust the bus number we are trying to access based
on which PCI controller its on
Patch by Kumar Gala 12 Jan 2006
Patch by Kumar Gala, 12 Jan 2006
* Report back PCI bus when doing table based device config
Patch by Kumar Gala 11 Jan 2006
Patch by Kumar Gala, 11 Jan 2006
* Added support for PCI prefetchable region and BARs
If a host controller sets up a region as prefetchable and

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.
