This is 2nd submission of Intel service layer and FPGA patches.

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 (5):
  firmware: stratix10-svc: add COMMAND_AUTHENTICATE_BITSTREAM flag
  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
