 *   @n@b CSL_memprotInit
 *
 *   @b Description
 *   @n This is the initialization function for the MEMPROT. This function is
 *      idempotent in that calling it many times is same as calling it once.
 *      This function initializes the CSL data structures, and doesn't affect
 *      the H/W. The function must be called before calling any other API from 
 *      this CSL.
 *
 *   @b Arguments
     @verbatim
            pContext   Context information for the instance. Should be NULL
     @endverbatim
 *
 *   <b> Return Value </b>  CSL_Status
 *   @li                    CSL_SOK - Always returns
 *
 *   <b> Pre Condition </b>
 *       This function should be called before using any of the CSL APIs
 *       in the Memory Protection module.
 *       
 *       Note: As Memory Protection doesn't have any context based information, 
 *       the function  just returns CSL_SOK. User is expected to pass NULL.
 *
 *   <b> Post Condition </b>
 *   @n  None
 *
 *   @b Modifies
 *   @n  None
 *
 *   @b Example
 *   @verbatim
      ...
         CSL_memprotInit();
     @endverbatim
 * ============================================================================
