Subject: [PATCH v1 00/12] Intel FPGA Security Manager Class Driver

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.
