    Subject[PATCHv3 0/6] [PATCHv3 0/6] Extend Intel service layer, FPGA manager and region
    Date
    From: Richard Gong <richard.gong@intel.com>

    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.

    Richard Gong (6):
    firmware: stratix10-svc: add COMMAND_AUTHENTICATE_BITSTREAM flag
    firmware: stratix10-svc: extend SVC driver to get the firmware version
    fpga: fpga-mgr: add FPGA_MGR_BITSTREM_AUTHENTICATION flag
    fpga: of-fpga-region: add authenticate-fpga-config property
    dt-bindings: fpga: add authenticate-fpga-config property
    fpga: stratix10-soc: extend driver for bitstream authentication
