The customer wants to verify that a FPGA bitstream can be started properly before saving the bitstream to the QSPI flash memory. Bitstream authentication makes sure a signed bitstream has valid signatures. The customer sends the bitstream via FPGA framework and overlay, the firmware will authenticate the bitstream but not program the bitstream to device. If the authentication passes, the bitstream will be programmed into QSPI flash and will be expected to boot without issues. Extend Intel service layer, FPGA manager and region drivers to support the bitstream authentication feature.
