-   Memory Mapped  MTD Routines
-   
-   These routines are support routines for memory mapped chips, with
-   routines to support common sorts of flash. For devices that are based
-   on a memory mapped interface these routines provide everything necessary,
-   only a window changing function is required by the low level implementation.
-   
-   The entry point to setup and register a memory mapped MTD device, 
-   mtd_mapped_setup will perform a detection sequence that can determine
-   the type size and configuration of many sorts of chip setups. 
-
-   ROMs and RAMs are detected and passed off to very simple routines, Flash
-   writing and erasing is handled as well.
