arm64: socfpga: merge Agilex and N5X into ARCH_INTEL_SOCFPGA Agilex, N5X and Stratix 10 share all quite similar arm64 hard cores and SoC-part. Up to a point that N5X uses the same DTSI as Agilex. From the Linux kernel point of view these are flavors of the same architecture so there is no need for three top-level arm64 architectures. Simplify this by merging all three architectures into ARCH_INTEL_SOCFPGA and dropping the other ARCH* arm64 Kconfig entries. The side effect is that the INTEL_STRATIX10_SERVICE will now be available for both 32-bit and 64-bit Intel SoCFPGA, even though it is used only for 64-bit.

fpga: add device feature list support Device Feature List (DFL) defines a feature list structure that creates a linked list of feature headers within the MMIO space to provide an extensible way of adding features. This patch introduces a kernel module to provide basic infrastructure to support FPGA devices which implement the Device Feature List. Usually there will be different features and their sub features linked into the DFL. This code provides common APIs for feature enumeration, it creates a container device (FPGA base region), walks through the DFLs and creates platform devices for feature devices (Currently it only supports two different feature devices, FPGA Management Engine (FME) and Port which the Accelerator Function Unit (AFU) connected to). In order to enumerate the DFLs, the common APIs required low level driver to provide necessary enumeration information (e.g. address for each device feature list for given device) and fill it to the dfl_fpga_enum_info data structure. Please refer to below description for APIs added for enumeration. Functions for enumeration information preparation: *dfl_fpga_enum_info_alloc allocate enumeration information data structure. *dfl_fpga_enum_info_add_dfl add a device feature list to dfl_fpga_enum_info data structure. *dfl_fpga_enum_info_free free dfl_fpga_enum_info data structure and related resources. Functions for feature device enumeration: *dfl_fpga_feature_devs_enumerate enumerate feature devices and return container device. *dfl_fpga_feature_devs_remove remove feature devices under given container device.

When Nios finishes the configuration, host takes over the ownership of the SPI master to control an Intel MAX10 BMC (Board Management Controller) Chip on the SPI bus. For Nios firmware handshake part, this driver requests the retimer configuration for Nios firmware on probe, and adds some sysfs nodes for user to query the onboard retimer's working mode and Nios firmware version. For SPI part, this driver adds a spi-altera platform device as well as the MAX10 BMC spi slave info. A spi-altera driver will be matched to handle the following SPI work.

Secure update support for the Intel MAX10 board management
controller.
This is a subdriver of the Intel MAX10 board management controller
(BMC) and provides support for secure updates for the BMC image,
the FPGA image, the Root Entry Hashes, etc.
