From: Richard Gong <richard.gong@xxxxxxxxx> This is 3rd submission of Intel service layer and FPGA patches. This submission include additional changes for Intel service layer driver to get the firmware version running at FPGA SoC device. Then FPGA manager driver, one of Intel service layer driver's client, can decide whether to handle the newly added bitstream authentication function based on the retrieved firmware version. So that we can maintain FPGA manager driver the back compatible. 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.
