QUP from version 2.1.1 onwards, supports a new format of i2c command tags. Tag codes instructs the controller to perform a operation like read/write. This new tagging version supports bam dma and transfers of more than 256 bytes without 'stop' in between. Adding the support for the same. For each block a data_write/read tag and data_len tag is added to the output fifo. For the final block of data write_stop/read_stop tag is used.
