This is a common question I think. Try looking for the following in drivers/pci/pci.c:
#define PCI_OP(rw,size,type) \ int pci_##rw##_config_##size (struct pci_dev *dev, int pos, type value) \ { \ [ ... ] }
PCI_OP(read, byte, u8 *) PCI_OP(read, word, u16 *) PCI_OP(read, dword, u32 *) PCI_OP(write, byte, u8) PCI_OP(write, word, u16) PCI_OP(write, dword, u32)
