- * \section Purpose
- *
- * Generic Media type, which provides transparent access to all types of
- * memories.
- *
- * \note The physical or HW related media operations (physical device
- * connection & protection detecting, PIO configurations and interface
- * driver initialization) are excluded.
- *
- * \section Usage
- * -# Do PIO initialization for peripheral interfaces.
- * -# Initialize peripheral interface driver & device driver.
- * -# Initialize specific media interface and link to this initialized driver.
