SubjectRE: [PATCHv5 0/7] Extend Intel service layer, FPGA manager and region
Hi Moritz,

Sorry for asking.

When you have chance, can you help review the version 5 patchset submitted on 02/09/21?

Subject: [PATCHv5 0/7] Extend Intel service layer, FPGA manager and region

From: Richard Gong <>

This is 5th submission of Intel service layer and FPGA patches, which includes the missing standalone patch in the 4th submission.

This submission includes 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.

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 (7):
firmware: stratix10-svc: reset COMMAND_RECONFIG_FLAG_PARTIAL to 0
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_BITSTREAM_AUTHENTICATE 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
