pci_read_base - read a PCI BAR : the PCI device : type of the BAR : resource buffer to be filled in : BAR position in the config space
Returns 1 if the BAR is 64-bit, or 0 if 32-bit.

pci_cfg_space_size - get the configuration space size of the PCI device. : PCI device
Regular PCI devices have 256 bytes, but PCI-X 2 and PCI Express devices have 4096 bytes. Even if the device is capable, that doesn't mean we can access it. Maybe we don't have a way to generate extended config space accesses, or the device is behind a reverse Express bridge. So we try reading the dword at 0x100 which must either be 0 or a valid extended capability header.

pci_scan_slot - scan a PCI slot on a bus for devices. : PCI bus to scan : slot number to scan (must have zero function.)
Scan a PCI slot on the specified PCI bus for devices, adding discovered devices to the ->devices list. New devices will not have is_added set.
Returns the number of new devices found.
Definition at line 1401 of file probe.c.
pci_setup_device - fill in class and map information of a device : the device structure to fill
Initialize the device structure with information about the device's vendor,class,memory and IO-space addresses,IRQ lines etc. Called at initialisation of the PCI subsystem and by CardBus services. Returns 0 on success and negative if unknown type of device (not normal, bridge or CardBus).
