These patches depend on the patchset: "add regmap-spi-avmm & Intel Max10 BMC chip support" which is currently under review. -------------------------------------------------- This patchset introduces the Intel Security Manager class driver for managing secure updates on Intel FPGA Cards. It also provides the n3000bmc-secure mfd sub-driver for the MAX10 BMC for the n3000 Programmable Acceleration Cards (PAC). The n3000bmc-secure driver is implemented using the Intel Security Manager class driver. The Intel Security Manager class driver provides a common API for user-space tools to manage updates for Secure FPGA devices. Device drivers that instantiate the Intel Security Manager class driver will interact with the HW secure update engine in order to transfer new FPGA and BMC images to FLASH so that they will be automatically loaded when the FPGA card reboots. The API consists of sysfs nodes and supports the following functions: (1) Instantiate and monitor a secure update (2) Display security information including: Root Entry Hashes (REH), Cancelled Code Signing Keys (CSK), and flash update counts for both BMC and FPGA images. Secure updates make use of the request_firmware framework, which requires that image files are accessible under /lib/firmware. A request for a secure update returns immediately, while the update itself proceeds in the context of a kernel worker thread. Sysfs files provide a means for monitoring the progress of a secure update and for retrieving error information in the event of a failure. The n3000bmc-secure driver instantiates the Intel Security Manager class driver and provides the callback functions required to support secure updates on Intel n3000 PAC devices.
