* Patch by Travis Sawyer, 09 Feb 2004:

o 440GX:
    - Fix PCI Indirect access for type 1 config cycles with ppc440.
    - Add phymode for 440 enet
    - fix pci pre init
  o XPedite1K:
    - Change board_pre_init to board_early_init_f
    - Add user flash to bus controller setup
    - Fix pci pre init
    - Fix is_pci_host to check GPIO for monarch bit
    - Force xpedite1k to pci conventional mode (via #define option)

* Patch by Brad Kemp, 4 Feb 2004:
  - handle the machine check that is generated during the PCI scans
    on 82xx processors.
  - define the registers used in the IMMR by the PCI subsystem.
