-/* what is the meaning of devfn in qemu and IDSEL in bonito northbridge?
- *
- * devfn   pci_slot<<3  + funno
- * one pci bus can have 32 devices and each device can have 8 functions.
- *
- * In bonito north bridge, pci slot = IDSEL bit - 12.
- * For example, PCI_IDSEL_VIA686B = 17,
- * pci slot = 17-12=5
- *
- * so
- * VT686B_FUN0's devfn = (5<<3)+0
- * VT686B_FUN1's devfn = (5<<3)+1
- *
- * qemu also uses pci address for north bridge to access pci config register.
- * bus_no   [23:16]
- * dev_no   [15:11]
- * fun_no   [10:8]
- * reg_no   [7:2]
- *
- * so function bonito_sbridge_pciaddr for the translation from
- * north bridge address to pci address.
