Subject: * 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.

* Patch by Pierre Aubert, 03 Feb 2004:
  cpu/mpc5xxx/start.S: copy MBAR into SPR311

* Patch by Jeff Angielski, 03 Feb 2004:
  Fix copy & paste error in cpu/mpc8260/pci.c

* Patch by Reinhard Meyer, 24 Jan 2004:
  Fix typo in cpu/mpc5xxx/pci_mpc5200.c
