The DDR controller data path is connected to the MSMC2DDR bridge through AXI interface. To enable higher performance and lower latency, the bridge drives the AXI AWALLSTRB signal to a "1" when the AXI write data do not have any byte enable holes. This allows the DDR controller to accept and start processing the write command as soon as possible without waiting for all data. The AXI0_ALL_STROBES_USED_ENABLE bit in the DDR Controller must be set to a 0x1 to utilize this feature. The controller ignores the AWALLSTRB signal if AXI0_ALL_STROBES_USED_ENABLE is set to 0x0.
