  • shared/motorola/motorola.c, shared/pci/detect_raven_bridge.c, shared/pci/pci.c, shared/pci/pci.h, shared/pci/pcifinddevice.c: Several PCI enhancements and fixes: all BSP flavors now use the generic clear_hostbridge_errors() routine (this means that only polling memory probing is possible [see detect_raven_bridge.c for details]). Interrupt fixup routine now supports multi-function devices. Interrupt fixup routine now honours a flag/option so that wrong firmware values can be overridden. Fixed irq routing table for mvme2100 [PMC]. Added irq routing table for mvme2300. Added a BSP_pciScan() routine that executes a user callback on each non-empty slot/fun. Added BSP_pciConfigDump() to display basic config headers.
