Eventuall your board just needs to be added to this #ifdef:

 684 #if defined(CONFIG_BAB7xx) || defined(CONFIG_CPC45)
 685         /*
 686          * Do PCI configuration on BAB7xx and CPC45 _before_ the flash
 687          * gets initialised, because we need the ISA resp. PCI_to_LOCAL bus
 688          * bridge there.
 689          */
 690         pci_init ();
 691 #endif


If this works for you, then please convert the #ifdef into a feature
#ifdef, say "CONFIF_SYS_EARLY_PCI_INIT".

Best regards,

Wolfgang Denk
