fpga: xilinx-selectmap: add new driver

2024-03-31T14:44:21+00:00

Xilinx 7 series FPGA can be programmed using a parallel port named the SelectMAP interface in the datasheet. This interface is compatible with the i.MX6 EIM bus controller but other types of external memory mapped parallel bus might work. xilinx-selectmap currently only supports the x8 mode where data is loaded at one byte per rising edge of the clock, with the MSb of each byte presented to the D0 pin.

fpga: xilinx-spi: extract a common driver core

2024-03-31T14:41:26+00:00

Factor out the gpio handshaking (using PROGRAM_B, INIT_B and DONE) protocol in xilinx-core so that it can be reused for another driver. This commit does not change anything functionally to xilinx-spi. xilinx-core expects drivers to provide a write(const char* buf, size_t count) function that performs the actual write to the device, as well as a struct device* for resource management.

mfd: intel-m10-bmc: Split into core and spi specific parts

2023-01-27T10:35:00+00:00

Split the common code from intel-m10-bmc driver into intel-m10-bmc-core and move the SPI bus parts into an interface specific file. intel-m10-bmc-core becomes the core MFD functions which can support multiple bus interface like SPI bus.

Pull char/misc driver updates from Greg KH: "Here is the large set of char/misc and other driver subsystem changes for 6.2-rc1. Nothing earth-shattering in here at all, just a lot of new driver development and minor fixes. Highlights include: - fastrpc driver updates - iio new drivers and updates - habanalabs driver updates for new hardware and features - slimbus driver updates - speakup module parameters added to aid in boot time configuration - i2c probe_new conversions for lots of different drivers - other small driver fixes and additions One semi-interesting change in here is the increase of the number of misc dynamic minors available to 1048448 to handle new huge-cpu systems.

fpga: m10bmc-sec: Fix kconfig dependencies

2022-11-15T13:46:58+00:00

The secure update driver depends on the firmware-upload functionality of the firmware-loader. The firmware-loader is carried in the firmware-class driver which is enabled with the tristate CONFIG_FW_LOADER option. The firmware-upload functionality is included in the firmware-class driver if the bool FW_UPLOAD config is set. The current dependency statement, "depends on FW_UPLOAD", is not adequate because it does not implicitly turn on FW_LOADER. Instead of adding a dependency, follow the convention used by drivers that require the FW_LOADER_USER_HELPER functionality of the firmware-loader by using select for both FW_LOADER and FW_UPLOAD.

fpga: m10bmc-sec: create max10 bmc secure update

2022-06-08T09:04:37+00:00

Create a sub-driver for the FPGA Card BMC in order to support secure updates. This patch creates the Max10 BMC Secure Update driver and provides sysfs files for displaying the root entry hashes (REH) for the FPGA 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 firmware and FPGA images are authenticated using ECDSA before loading and executing on the card. Code Signing Keys (CSK) are used to sign images. CSKs are signed by a root key. The root entry hash is created from the root public key. The RoT provides authentication by storing an REH bitstream to a write-once location. Image signatures are verified against the hash.
