2023-03-23soc/intel/elkhartlake: Define DIMM_SPD_SIZE in SoC KconfigMichał Żygowski
The default SPD size is set to 256 bytes, instead of 512 for LPDDR4/DDR4 if not overridden by the mainboard Kconfig. This caused the SMBus libraries to read only the lower half of the DIMM SPD on protectli/vault_ehl. The lower half of the SPD passed to FSP causes a bug in DIMM change detection, which relies on the CRC of the manufacturer bytes in the upper half of the SPD (CRC of zero bytes always gives zero so no change was assumed). Setting the DIMM SPD size to 512 fixes it. Setting the SPD size in SoC will also avoid such problems in the future Elkhart Lake ports. Elkhart Lake supports only LPDDR4/DDR4 so providing the correct default of 512 bytes is an obvious thing to do. TEST=Boot Protectli VP2420 (vault_ehl) with different DIMMs and see FSP is retraining the memory instead of doing the fastboot with old DIMM data.

For recent X86 CPUs, the 0x15 CPUID instruction will return Time Stamp Counter Frequence. For CPUs that do not support this instruction, EDK2 must include a different library which is the reason why this must be configured at build time. If this is enabled, and the CPU doesn't support 0x15, it will fail to boot. If is not enabled, and the CPU does support 0x15, it will still boot but without support for the leaf. Consequently, disabled it by default.

2022-01-25soc/intel/ehl: Add Kconfig option to disable reset on TCO expirationWerner Zeh
The TCO timer is the default watchdog of an x86 host and can reset the system once it has expired for the second time. There are applications where this reset is not acceptable while the TCO is used. In these applications the TCO expire event generates an interrupt and software takes care. There is a bit in the TCO1_CNT register on Elkhart Lake to prevent this reset on expiration (called NO_REBOOT, see doc #636722 ). This bit can either be strapped on hardware or set in this register to avoid the reset on expiration. While the hardware strap cannot be overridden in software, the pure software solution is more flexible. Unfortunately, the location for this bit differs among the different platforms. This is why it has to be handled on soc level rather than on TCO common code level. This commit adds a Kconfig option where NO_REBOOT can be enabled. This makes it easy to reach this feature over to the mainboard where it can be selected if needed.

2022-01-25soc/intel/elkhartlake: Introduce Intel PSELean Sheng Tan
The Intel® Programmable Services Engine (Intel® PSE) is a dedicated offload engine for IoT functions powered by an ARM Cortex-M7 microcontroller. It provides independent, low-DMIPS computing and low-speed I/Os for IoT applications, plus dedicated services for real-time computing and time-sensitive synchronization. The PSE hosts new functions, including remote out-of-band device management, network proxy, embedded controller lite and sensor hub. This CL enables the user to provide the base address of the PSE FW blob which will then be loaded by the FSP-S onto the ARM controller. PSE FW will do the initialization work of PSE controller and its peripherals. The loading of PSE FW should have negligible impact on boot time unless PSE controller could not locate the PSE FW and FSP will attempt to redo PSE FW loading and wait for PSE handshake until it times out. Once PSE controller locate the PSE FW, it will do initialization concurrently by itself with coreboot booting. It also adds PSE related FSP-S UPD settings which enable the setup of peripheral ownership (assigned to the PSE or x86 subsystem) and interrupts. These assignments need to take place at a given point in the boot process and cannot be changed later. To verify if PSE FW is loaded properly, the user could enable PchPseShellEnabled flag and the log will be printed at PSE UART 2. For further info please refer to doc #611825 (for HW overview) and #614110 (for PSE EDS).

Instead of using the indirect path of selecting MP PPI services, this change allows SoC to select FSP_USES_MP_SERVICES_PPI directly. The above uses are handled as follows: * Auto-selecting FSP_USES_MP_SERVICES_PPI --> This is handled by SoC selection of FSP_USES_MP_SERVICES_PPI. * Including src/drivers/intel/fsp2_0/ppi/Kconfig --> The guard isn't really required. The Kconfig options in this file don't present user prompts and don't really need to be guarded. * Adding ppi to subdirs-y --> Makefile under ppi/ already has conditional inclusion of files and does not require a top-level conditional. * Setting USE_INTEL_FSP_TO_CALL_COREBOOT_PUBLISH_MP_PPI to y --> This is set to y if FSP_USES_MP_SERVICES_PPI is selected by SoC.
