This looks very much like a prototype definition to me.
OK. It defines perfectly BUT where is the function pci_hose_read_config_byte() body? Only declaration is not enought to use it......
Thanks,

The code is where it is to be expected - in "drivers/pci.c":
#define PCI_HOSE_OP(rw, size, type) \ int pci_hose_##rw##_config_##size(struct pci_controller *hose, \ pci_dev_t dev, \ int offset, type value) \ { \ return hose->rw##_##size(hose, dev, offset, value); \ }
PCI_HOSE_OP(read, byte, u8 *) PCI_HOSE_OP(read, word, u16 *) PCI_HOSE_OP(read, dword, u32 *) PCI_HOSE_OP(write, byte, u8) PCI_HOSE_OP(write, word, u16) PCI_HOSE_OP(write, dword, u32)
Sometimes even "grep" cannot save you from actually RTFS ;-)
