Microchip Technology has contributed the DeviceTree support for the PolarBerry board that includes the PolarFire SoC FPGA for FPGA capabilities paired with a 64-bit RISC-V multi-core processor. The mainline Linux kernel has already seen PolarFire SoC support while now the PolarBerry is the latest supported board based on it.
