/*
 * dspapi.h
 *
 * DSP-BIOS Bridge driver support functions for TI OMAP processors.
 *
 * Includes the wrapper functions called directly by the
 * DeviceIOControl interface.
 *
 * Notes:
 *   Bridge services exported to Bridge driver are initialized by the DSPAPI on
 *   behalf of the Bridge driver. Bridge driver must not call module Init/Exit
 *   functions.
 *
 *   To ensure Bridge driver binary compatibility across different platforms,
 *   for the same processor, a Bridge driver must restrict its usage of system
 *   services to those exported by the DSPAPI library.
