/*  void Shm_Get_configuration( localnode, &shmcfg )
 *
 *  This routine initializes, if necessary, and returns a pointer
 *  to the Shared Memory Configuration Table for the XXX target.
 *
 *  INPUT PARAMETERS:
 *    localnode - local node number
 *    shmcfg    - address of pointer to SHM Config Table
 *
 *  OUTPUT PARAMETERS:
 *    *shmcfg   - pointer to SHM Config Table
 *
XXX: FIX THE COMMENTS BELOW WHEN THE CPU IS KNOWN
 *  NOTES:  The XYZ does not have an interprocessor interrupt.
 *
 *          The following table illustrates the configuration limitations:
 *
 *                                   BUS     MAX
 *                          MODE    ENDIAN  NODES
