/*******************************************************************************
* mvDmaMemInit - Initialize a memory buffer with a given 64bit value pattern
* 
* DESCRIPTION:       
*       This function initiates IDMA channel, according to function parameters,
*       in order to perform DMA transaction for the purpose of initializing a 
*       memory buffer with a user supplied pattern.
*       This routine supports both chain and none chained DMA modes. 
*       To use the function in chain mode just set phyNextDesc parameter with
*       chain second descriptor address (the first one is given in other 
*       function paarameters). Otherwise (none chain mode) set it to NULL.
*       To gain maximum performance the user is asked to keep the following 
*       restrictions:
*       1) Selected engine is available (not busy).
*       1) This module does not take into consideration CPU MMU issues.
*          In order for the IDMA engine to access the appropreate source 
*          and destination, address parameters must be given in system 
*          physical mode.
*       2) This API does not take care of cache coherency issues. The source,
*          destination and in case of chain the descriptor list are assumed
*          to be cache coherent.
*       3) No chain mode support.
*       4) Parameters validity. For example, does size parameter exceeds 
*          maximum byte count of descriptor mode (16M or 64K).
*
* INPUT:
*       chan          - DMA channel number. See MV_DMA_CHANNEL enumerator.
*       ptrnPtr       - Physical source address of the 64bit pattern
*       startPtr      - Physical destinaation address to start with
*       size          - The total number of bytes to transfer.
*
* OUTPUT:
*       None.
*
* RETURS:
*       MV_OK.
