 *
 *   @b Arguments
 *   @verbatim
            hAta            Handle to the ATA instance

            config          Pointer to config structure
     @endverbatim
 *
 *   <b> Return Value </b>  CSL_Status
 *   @li            CSL_SOK               - Configuration successful
 *   @li            CSL_ESYS_BADHANDLE    - Invalid handle
 *   @li            CSL_ESYS_INVPARAMS    - Configuration is not
                                            properly initialized
 *   <b> Pre Condition </b>
 *   @n  None
 *
 *   <b> Post Condition </b>
 *   @n  The registers of the specified ATA instance will be setup
 *       according to input configuration structure values.
