The AXI master interface transfers boot code from the NAND flash memory to the system memory during system power-up. The NAND flash controller acts as a master during a memory DMA mode of transaction. When the AXI master interface places control signals on the AXI bus depends upon the FIFO status. During a write transaction, the AXI master interface reads data from system memory and stores it in the FIFO. During a read transaction, the AXI master interface reads data from the FIFO and writes data into system memory. The AXI master interface asserts a DMA interrupt when the DMA buffer boundary is reached.

The DMA memory transactions will be routed to the CCI.
