* 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
