> +# Background
> +
> +The IO device API is a interface to access IO address spaces via a device node
> +and a file descriptor obtained after opening the device node. A registered IO
> +driver provide a mapping from a logical identifier to a specific address where
> +an IO device resides. The API does not directly interact with an device hardware.
> +An application can use a common identifier to a local IO address map for a
> +device who's address can vary depending on a bus configuration or the BSP hardware.
