* FUNCTION:
*    PlatformSWInit
*
* DESCRIPTION:
*    This routine calls the software initialization entry points for all the
*    supported device drivers on Mainstone.
*
* INPUT PARAMETERS:
*    None.
*
* RETURNS:
*    None.
*
* GLOBAL EFFECTS:
*    The Mainstone device drivers are initialized and ready to setup the
*    hardware devices.
*
* ASSUMPTIONS:
*    The device driver initialization is intended to initialize only the driver
*    not the hardware. Hardware initialization should be done in the routine
*    PlatformHWSetup.
*
* CALLS:
*    All Mainstone device driver software initialization routines.
*
* CALLED BY:
*
* PROTOTYPE:
*    VOID PlatformSWInit(VOID);
