+What: /sys/bus/pci/drivers/.../bind
+Date: December 2003
+Contact: linux-pci@vger.kernel.org
+Description:
+ Writing a device location to this file will cause
+ the driver to attempt to bind to the device found at
+ this location. This is useful for overriding default
+ bindings. The format for the location is: DDDD:BB:DD.F.
+ That is Domain:Bus:Device.Function and is the same as
+ found in /sys/bus/pci/devices/. For example:
+ # echo 0000:00:19.0 > /sys/bus/pci/drivers/foo/bind
+ (Note: kernels before 2.6.28 may require echo -n).

+Date: December 2003

+Description:
+ Writing a device ID to this file will attempt to
+ dynamically add a new device ID to a PCI device driver.
+ This may allow the driver to support more hardware than
+ was included in the driver's static device ID support
+ table at compile time. The format for the device ID is:
+ VVVV DDDD SVVV SDDD CCCC MMMM PPPP. That is Vendor ID,
+ Device ID, Subsystem Vendor ID, Subsystem Device ID,
+ Class, Class Mask, and Private Driver Data. The Vendor ID
+ and Device ID fields are required, the rest are optional.
+ Upon successfully adding an ID, the driver will probe
+ for the device and attempt to bind to it. For example:
+ # echo "8086 10f5" > /sys/bus/pci/drivers/foo/new_id
+

On all platforms, the firmware provides a memory map which the
kernel reads. The resources from that memory map are registered
