On DFL FPGA devices, the Accelerated Function Unit (AFU), can be reprogrammed for different functions. It connects to the FPGA infrastructure (static FPGA region) via a Port. Port CSRs are implemented separately from the AFU CSRs to provide control and status of the Port. Once valid PR bitstream is programmed into the AFU, it allows access to the AFU CSRs in the AFU MMIO space. This patch only implements basic driver framework for AFU, including device file operation framework.
