    You can also find at the bottom of this file a few convernient
    macros that will create the stub read and/or write handlers for
    the most common mappings, that will use the functions above.
    Here's an example on how to use them: Say you have a 8 bit device
    whose handlers are device8_r and device8_w, and you want to connect
    it to a 16 bit, big endian cpu. We'll say the device is mapped on
    the least significant byte of the data bus (LSB).

    In your driver, you would add:

    READWRITE8TO16BE_LSB( device16, device8_r, device8_w )

    which will create two 16 bit memory handlers, one for read, called
    device16_r, and one for write, called device16_w, with the proper
    mapping.

    then in the MEMORY_MAP you would specify:

    AM_RANGE(0x000000, 0x0000ff) AM_READWRITE( device16_r, device16_w )

    And that is all. Your device should be mapped properly.
    If you need to do custom mappings, or a mapping that is not currently
    supported in this file, you can always write the stub yourself, and
    call the above functions to invoke the base handlers.
