Enable 32-bit or 64-bit DMA in the macb driver based on the macb hardware compatibility and it is configured with structure macb_config in the driver. The Microchip PolarFire SoC Memory Protection Unit(MPU) gives the 64-bit DMA access with the GEM, the MPU transactions on the AXI bus is 64-bit not 32-bit So 64-bit DMA is enabled for the Microchip PolarFire SoC GEM.
