This change checks¹ if the system does not have a br0 interface, creates a default one consisting of all switch ports in VLAN 1 of br0. On top of br0 a vlan1 management interface is created with DHCP address. For emulation and test purposes, a way to supply tap interfaces from Qemu, and pass off as if they were regular switch ports, is added. ____ ¹ obviously a better way to detect a factory-reset device is needed, not all systems running infix will need or want a br0 interface.

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
- Don't load a corrupt bootloader to begin with
- 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):

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
