Thu, 16 Apr 2026 16:42:36 +0200

fpga-mgr: Add Efinix SPI programming driverAdd a new driver for loading binary firmware to configurationRAM using "SPI passive mode" on Efinix FPGAs.Efinix passive SPI configuration requires chip select to remain assertedfrom reset until the complete bitstream and trailing idle clocks havebeen transferred, so the driver keeps CS active with cs_change and locksthe SPI bus for the duration of configuration.Signed-off-by: Ian Dannapel Reviewed-by: Xu Yilun Link: https://lore.kernel.org/r/20260416144237.373852-4-iansdannapel@gmail.comSigned-off-by: Xu Yilun List of files: /linux/drivers/fpga/Kconfig

Thu, 21 Mar 2024 23:04:35 +0100

fpga: xilinx-selectmap: add new driverXilinx 7 series FPGA can be programmed using a parallel port namedthe SelectMAP interface in the datasheet. This interface is compatiblewith the i.MX6 EIM bus controller but other types of external memorymapped parallel bus might work.xilinx-selectmap currently only supports the x8 mode where data is loadedat one byte per rising edge of the clock, with the MSb of each bytepresented to the D0 pin.Signed-off-by: Charles Perry [yilun.xu@linux.intel.com: replace data type of i from u32 to size_t]Acked-by: Xu Yilun Link: https://lore.kernel.org/r/20240321220447.3260065-4-charles.perry@savoirfairelinux.comSigned-off-by: Xu Yilun List of files: /linux/drivers/fpga/Kconfig

fpga: m10bmc-sec: Fix kconfig dependenciesThe secure update driver depends on the firmware-upload functionality ofthe firmware-loader. The firmware-loader is carried in the firmware-classdriver which is enabled with the tristate CONFIG_FW_LOADER option. Thefirmware-upload functionality is included in the firmware-class driver ifthe bool FW_UPLOAD config is set.The current dependency statement, "depends on FW_UPLOAD", is not adequatebecause it does not implicitly turn on FW_LOADER. Instead of adding adependency, follow the convention used by drivers that require theFW_LOADER_USER_HELPER functionality of the firmware-loader by usingselect for both FW_LOADER and FW_UPLOAD.Fixes: bdf86d0e6ca3 ("fpga: m10bmc-sec: create max10 bmc secure update")Reported-by: kernel test robot Cc: stable@vger.kernel.orgSigned-off-by: Russ Weight Acked-by: Randy Dunlap Acked-by: Xu Yilun Link: https://lore.kernel.org/r/20221115001127.289890-1-russell.h.weight@intel.comSigned-off-by: Xu Yilun List of files: /linux/drivers/fpga/Kconfig

fpga: m10bmc-sec: create max10 bmc secure updateCreate a sub-driver for the FPGA Card BMC in order to support secureupdates. This patch creates the Max10 BMC Secure Update driver andprovides sysfs files for displaying the root entry hashes (REH) for theFPGA static region (SR), the FPGA Partial Reconfiguration (PR) region,and the card BMC.The Intel MAX10 BMC Root of Trust (RoT) requires that all BMC Nios firmwareand FPGA images are authenticated using ECDSA before loading and executingon the card. Code Signing Keys (CSK) are used to sign images. CSKs aresigned by a root key. The root entry hash is created from the root publickey.The RoT provides authentication by storing an REH bitstream to a write-oncelocation. Image signatures are verified against the hash.Reviewed-by: Tom Rix Tested-by: Tianfei Zhang Signed-off-by: Russ Weight Link: https://lore.kernel.org/r/20220606160038.846236-3-russell.h.weight@intel.comSigned-off-by: Xu Yilun List of files: /linux/drivers/fpga/Kconfig

fpga: dfl: add support for N3000 Nios private featureThis patch adds support for the Nios handshake private feature on IntelPAC (Programmable Acceleration Card) N3000.The Nios is the embedded processor on the FPGA card. This private featureprovides a handshake interface to FPGA Nios firmware, which receivesretimer configuration command from host and executes via an internal SPImaster (spi-altera). When Nios finishes the configuration, host takes overthe ownership of the SPI master to control an Intel MAX10 BMC (BoardManagement Controller) Chip on the SPI bus.For Nios firmware handshake part, this driver requests the retimerconfiguration for Nios firmware on probe, and adds some sysfs nodes foruser to query the onboard retimer's working mode and Nios firmwareversion.For SPI part, this driver adds a spi-altera platform device as well asthe MAX10 BMC spi slave info.
