-   knowledge of specific devices.  Historically board init routines have
-   passed a bunch of arguments to each device, requiring the board know
-   exactly which device it is dealing with.  This file provides an abstract
-   API for device configuration and initialization.  Devices will generally
-   inherit from a particular bus (e.g. PCI or I2C) rather than
-   this API directly.  */
