The QPIC NAND BAM has multiple flags to control the transfer. This patch adds flags parameter in register and data transfer DMA helper functions and modifies all these functions call with appropriate flags using following rule 1. Read and write can’t go in single command descriptor so separate SGL should be used. 2. For some of the requests, NWD flag should be set in BAM DMA descriptor. 3. For Data write, the BAM has internal buffer for each codeword. All write request will modify the data in internal buffer and this buffer will be flushed to NAND device once EOT flag is set. So for all the write requests in single codeword, the EOT should be cleared for all tx data descriptors except the last one.
