      7  * File:        sum_pack.c
      8  * Purpose:     SUM pack and unpack routines for:
      9  *              - SUM Control messages
     10  *
     11  * SUM control messages
     12  *
     13  * SUM messages between the Host CPU and uController are sent
     14  * using the uc_message module which allows short messages
     15  * to be passed (see include/soc/shared/mos_msg_common.h)
     16  *
     17  * Additional information for a given message (a long message) is passed
     18  * using DMA.  The SUM control message types defines the format
     19  * for these long messages.
     20  *
     21  * This file is shared between SDK and uKernel.
