NOTE: The patch is untested. All MPC83xx FSL boards I have have PCI1 in miniPCI form, for which I don't have any cards handy. But looking in cpu/mpc85xx/pci.c: ... #ifdef CONFIG_MPC85XX_PCI2 hose = &pci_hose[1]; hose->first_busno = pci_hose[0].last_busno + 1; And considering that we do the same for MPC83xx PCI-E support, I think this patch is correct.
