+ * DESCRIPTION:
+ * This function initiates XOR channel, according to function parameters,
+ * in order to perform XOR or CRC32 or DMA transaction.
+ * 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 XOR 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.
+ * 4) Parameters validity. For example, does size parameter exceeds
+ * maximum byte count of descriptor mode (16M or 64K).
+ *
+ * INPUT:
+ * chan - XOR channel number. See MV_XOR_CHANNEL enumerator.
+ * xor_type - One of three: XOR, CRC32 and DMA operations.
+ * xor_chain_ptr - address of chain pointer
+ *
+ * OUTPUT:
+ * None.
+ *
+ * RETURS:
+ * MV_BAD_PARAM if parameters to function invalid, MV_OK otherwise.
