- *
- * 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

- *
- * qemu also uses pci address for north bridge to access pci config register.

- * fun_no [10:8]
- * reg_no [7:2]
