Tobias WaldekranzandJoachim Wiberg 3d8b64f939 aarch64: kernel: Enable DCB
In order to make use of the DCB support in mv88e6xxx we also enable it
in the kernel config.

aarch64

Microchip SparX-5i PCB135 (eMMC)

At present, only FIT images are supported via the SparX-5i eval board's U-Boot, which must contain a valid load address. If you are using this board, after selecting your base configuration, run the following command to supplement the existing config with the required FIT options:

make board-enable-sparx-fit

Unbricking

  1. Don't load a corrupt bootloader to begin with
  2. Done

If, for some reason, you didn't manage to follow step 1, you can use the FLASH_PROG(J4) connector on the board to access the SPI flash directly.

Using a Bus Blaster in combination with dangerspi, you can load a new bootloader. The schematic below details how to connect the Bus Blaster to the board, but the concept should be portable to any debugger/device based around an FTDI2232 chip.

Bus Blaster:         FLASH_PROG (J4):
       .---.              .---.

TCK SCK

With the cable in place, build U-Boot with the correct configuration:

make fireant_boot_defconfig && make

To flash it to the board, connect the cable to J4 and run:

make board-sparx-flash-uboot
