11 * fulong 2e mini pc has a bonito north bridge.
14 /* what is the meaning of devfn in qemu and IDSEL in bonito northbridge?
16 * devfn pci_slot<<3 + funno
17 * one pci bus can have 32 devices and each device can have 8 functions.
19 * In bonito north bridge, pci slot = IDSEL bit - 12.
20 * For example, PCI_IDSEL_VIA686B = 17,
24 * VT686B_FUN0's devfn = (5<<3)+0
25 * VT686B_FUN1's devfn = (5<<3)+1
27 * qemu also uses pci address for north bridge to access pci config register.
33 * so function bonito_sbridge_pciaddr for the translation from
34 * north bridge address to pci address.
