- * Each driver specifies a name, the bus-scanning function
- * (find_bus_boot_device) that it wants to use, a driver information
- * structure (bus_driver) containing e.g. device IDs to be passed to
- * find_bus_boot_device, and a probe function (probe) to be called
- * whenever a suitable device is found.
+ * Each bus driver defines several methods, which are described in
+ * dev.h. This file provides a centralised, bus-independent mechanism
+ * for locating devices and drivers.
*
- * The generic device-probing code knows nothing about particular bus
- * types; it simply passes the driver information structure
- * (bus_driver) to the bus-scanning function (find_bus_boot_device),
- * then passes the result of that function (if not NULL) to the probe
- * function (probe).
