To fix this you need to add the SPI devices on the SPI bus. Second, while the SPI buses are correctly initialized, if you tried to use them in Linux, you'd find that the chip-selects won't work. If you see complications with Serial port ordering, physically moving the serial ports within AMBA-PL will change the order they are initialized. Immediately, you should make sure that the last two numbers in the aliases for the Serial ports ends around serial6, the others will be reassigned when Linux starts up. AMBA-PL (All the other peripherals that are on the FPGA).AMBA (All the peripherals that are connected to the ARM processor).Aliases (Somewhat determines the names for device files).On all Xilinx platforms from u-boot, you can use SF command to. details (This section doesn't have a name, but contains: address-cells, size-cells, compatible) U-Boot provides the SF command to program serial flash devices.Open the generated Device Tree, the basic layout should be:
