2023-01-11soc/intel/elkhartlake: Provide a way to enable real-time tuningWerner Zeh
Intel provides a Real-Time Tuning Guide for Elkhart Lake to improve real-time behaviour of the SoC (see Intel doc #640979). It describes, amongst knobs for the OS, a couple of firmware settings that need to be set properly to reduce latencies in all the subsystems. Things like clock and power gating as well as low power states for peripherals and buses are disabled in this scenario. This patch takes the mentioned UEFI parameters from the guide and translates them to FSP-M and FSP-S parameters. In addition, a chip config switch guards this tuning which can be selected on mainboard level if needed. When this real-time tuning is enabled, the overall system performance in a real-time environment can be increased by 2-3%.

2023-01-10soc/intel/elkhartlake: Make SATA speed limit configurableWerner Zeh
In cases where there are limitations on the mainboard it can be necessary to limit the used SATA speed even though both, the SATA controller and disk drive support a higher speed rate. The FSP parameter 'SataSpeedLimit' allows to set the speed limit. This patch provides a chip config so that this FSP parameter can be set as needed in the devicetree on mainboard level.

2022-11-17soc/intel: Add node_num to dimm_info struct + adjust dimm_info_fillDavid Milosevic
The dimm_info structure (defined in src/include/memory_info.h) currently does not hold information about the DIMM's node/controller ID. This patch extends the dimm_info structure by adding a new field for the node ID, called node_num. Also, adapt the dimm_info_fill() function accordingly to populate the newly-added field. Background: These changes are necessary for the Atlas mainboard, where we are currently experiencing issues with the DIMMs device/bank locator. Our 2 DIMMs share the same CHANNEL and DIMM ID but have a distinct NODE ID. By looking at the smbios table we see Channel-0-DIMM-0 for both DIMMs. Thus, we need their NODE IDs in order to distinguish them. This patch was tested by building and booting for the Alderlake-P RVP board, which has the same DIMM slot configuration as the Prodrive Atlas mainboard.

2022-10-25soc/intel/elkhartlake: Fix incorrect divider for MDIO clockWerner Zeh
After some measurements it turned out that Elkhart Lake uses a higher CSR clock internally from which the MDIO clock is derived. In order to stay compliant with the specification, the MDIO clock needs to be lower than 2.5 MHz. Therefore, the divider needs to be 102 and not 62. This patch changes the define to match the new divider value and uses this new define at the appropriate place. Test=Measure the MDIO clock rate on mc_ehl2 which results in 2 MHz.

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.

2022-09-22soc/intel/spi: Move BIOS flash SPI controllers to fast SPI driverWerner Zeh
There are two classes of SPI controllers on Intel chipsets: * generic usable SPI controllers * SPI controller hosting the BIOS flash (fast SPI controller) While the first class can be used for generic peripheral attachment the second class mostly controls the BIOS flash and a TPM device (if enabled). The generic SPI driver is not fully applicable to the fast SPI controller. In addition, the fast SPI controller reports the reserved MMIO range used for the BIOS flash mapping so that the OS is aware of this range. This patch moves the fast SPI controller of all known SoCs to the fast SPI driver in common code. In addition, the PCI device for the fast SPI controller is removed from the function 'spi_soc_devfn_to_bus' as this is a callback of the generic SPI driver.

2022-02-25intelblocks/pcie: Correct mapping between LCAP port and coreboot indexMAULIK V VAGHELA
coreboot uses port index which is 0 based for all PCIe root ports. In case of PCIe remapping logic, coreboot reads LCAP register from PCIe configuration space which contains port number (mostly 1 based). This assumption might not be true for all the ports in coreboot. TBT's LCAP registers are returning port index which are based on 2. coreboot's PCIe remapping logic returns port index based on index 1. This patch adds variable to pcie_rp_config to pass lcap_port_base to the pcie remapping function, so coreboot can map any n-based LCAP encoding to 0-based indexing scheme. This patch updates correct lcap_port_base variable for all PCIe root ports for all SOCs, so that function returns correct 0-based index from LCAP port number.

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).

2021-11-24soc/intel/elkhartlake: Disable Intel PSE by defaultLean Sheng Tan
Disable PSE loading by default. If left enabled (current default), the EHL coreboot will end up in endless restart loop, due to FSP unable to locate PSE FW image and trigger global reset. However disabling this flag (PchPseEnable) will cause the coreboot to trigger a single reset due to CSE signal (HECI: CSE does not meet required prerequisites). The reason behind this is that FSP need to perform static disabling (power gate) to fully shut down PSE HW, and to do this will need to global reset entire system including CSE. Then PMC will power gate PSE from the start. To avoid this behavior, the best way to disable PSE is to disable via IFWI FIT softstrap (For specific detail can refer to Intel EHL coreboot MR2 release notes). With this, PMC will power gate PSE from the first cold boot and system will boot happily without single reset behavior.

Technically, it's not depending on the hardware but on the software (OS/payload), if the PM Timer is optional. OSes with ACPI >= 5.0A support disabling of the PM Timer, when the respective FADT flag is unset. Thus, drop this guard. For platforms without hardware PM Timer (Apollo Lake, Gemini Lake) the Kconfig `USE_PM_ACPI_TIMER` depends on `!NO_PM_ACPI_TIMER`. As of this change, new platforms must either implement code for disabling the hardware PM timer or select `NO_PM_ACPI_TIMER` if no such is present.

Comparing which CPU/SoC Makefiles added (cpu/)x86/mtrr and (cpu/)x86/lapic before this and the corresponding MTRR code selection patch and having verified that all platforms added the MTRR code on that patch shows that soc/example/min86 and soc/intel/quark are the only platforms that don't end up selecting the LAPIC code.

All x86-based CPUs and SoCs in the coreboot tree end up including the Makefile in cpu/x86/mtrr, so include this directly in the Makefile in cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is selected be default could be added and the new CPU/SoC without MTRR support can override this option that then will be used in the Makefile to guard adding the Makefile from the cpu/x86/mtrr sub-directory. In cpu/intel all models except model 2065X and 206AX are selcted by a socket and rely on the socket's Makefile.inc to add x86/mtrr to the subdirs, so those models don't add x86/mtrr themselves. The Intel Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the subdirs. The Intel Xeon SP SoC directory contains two sub-folders for different versions or generations which both add x86/mtrr to the subdirs in their Makefiles.

2021-09-20soc/intel/elkhartlake: Clear RTC_BATTERY_DEADTim Wawrzynczak
Normally for vboot-enabled x86 board, the VBNV region is stored in CMOS and backed up to flash (RW_NVRAM). However, on the very first boot after a flash of the full SPI image (so RW_NVRAM is empty), if RTC_BATTERY_DEAD is set, coreboot persistently requests recovery before FSP-M finishes (which appears to be the current location that RTC_BATTERY_DEAD is cleared on this platform). This is because vbnv_cmos_failed() will still return 1. Therefore, immediately after reading RTC_BATTERY_DEAD, it is cleared. This prevents an infinite boot loop when trying to set the recovery mode bit. Note that this was the behavior for previous generations of Intel PMC programming as well (see southbridge/intel, soc/skylake, soc/broadwell, etc).

The code under `cpu/x86/tsc` is only compiled in when its `Makefile.inc` is included from platform (CPU/SoC) code and the `UDELAY_TSC` Kconfig option is enabled. Include `cpu/x86/tsc/Makefile.inc` once from `cpu/x86/Makefile.inc` and drop the now-redundant inclusions from platform code. Also, deduplicate the `UDELAY_TSC` guards.
