In order to cache the spd data which reads from the memory module, we add SPD_CACHE_ENABLE option to enable the cache for the spd data. If this option is enabled, the RW_SPD_CACHE region needs to be added to the flash layout for caching the data. Since the user may remove the memory module after the bios caching the data, we need to add the invalidate flag to invalidate the mrc cache.

Currently the LPIT Get Constraints _DSM subfunction returns a package containing the path to a nonexistent device (\NULL). This is used to work around an issue with Windows, where returning an empty package will cause a BSOD.

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.

Commit 805956bce [soc/intel/cnl: Use Kconfig to disable HECI1] moved HECI1 disablement out of mainboard devicetree and into SoC Kconfig, but in doing so inadvertently disabled HECI1 for Puff-based boards which previously had HECI1 enabled by default.

Device driver is removed by 'rmmod' command. 2. Device _RST is called. _RST perform reset. 3. Device increments OFSK in _RST to skip the following _OFF invoked by OSPM. 4. OSPM invokes _OFF at the end of driver removal. 5. _OFF sees OFSK and skips current execution and decrements OFSK so that _OFF will be executed normally next time. 6. _OFF increments ONSK to skip the following _ON invoked by OSPM. 7. Device driver is reloaded by 'insmod/modprobe' command. 8. OSPM invokes _ON at the beginning of driver loading. 9. _ON sees ONSK and skip current execution and decrements ONSK so that _ON will be executed normally next time. - In normal case: When suspend, OSPM invokes _OFF. Since OFSK is zero, the device goes to deeper state as expected. When resume, OSPM invokes _ON. Sinc ONSK is zero, the device goes to active state as expected. - Generated changes: PowerResource (RTD3, 0x00, 0x0000) Name (ONSK, Zero) Name (OFSK, Zero) ...

2022-01-28soc/intel: Abstract the common block API for TCSS registers accessJohn Zhao
The existing TCSS registers access is through the REGBAR. There will be future platforms which access the TCSS registers through the Sideband interface. This change abstracts the common block API for TCSS access. BUG=b:213574324 TEST=Build platforms coreboot images successfully.

2022-01-28soc/intel/common/cse: skip heci_init() if HECI1 is disabledMatt DeVillier
If the HECI1 PCI device is disabled, either via devicetree or other method (HAP, me_cleaner), then we don't want/need to program a BAR, set the PCI config, or call heci_reset(), as the latter will result in a 15s timeout delay when booting. Test: build/boot Purism Librem 13v2, verify heci_reset() timeout delay is no longer present.

2022-01-28soc/intel/alderlake: Enable CPPCv3Sridahr Siricilla
The patch defines the following helper functions: get_cpu_scaling_factor(): Returns scaling factors of big and small core. cpu_is_nominal_freq_supported(): Returns true if CPU supports Nominal Frequency, otherwise false. cpu_is_nominal_freq_supported(): Check CPU supports nominal frequency or not. The patch also enables CPPCv3 support for Intel Alder Lake which is based on hybrid core architecture. TEST=Verified Nominal Frequency and Nominal Performance are getting updated for ADL-P small and big cores correctly.

2022-01-28soc/intel/common: Implement ACPI CPPCv3 package to support hybrid coreSridhar Siricilla
The patch implements ACPI CPPCv3 package. It implements and updates the following methods: generate_cppc_entries(): Updates method to support CPPCv3 package acpi_get_cpu_nominal_freq(): Calculates CPU's nominal frequency acpi_get_cpu_nomi_perf(): Calculates nominal performance for big and small cores. acpigen_write_CPPC_hybrid_method(): It generates ACPI code to implement _CPC method. acpigen_cppc_update_nominal_freq_perf(): It updates CPPC3 package if cpu supports Nominal Frequency. It generates ACPI code which sets Nominal Frequency and updates Nominal Performance. It uses below calculation to update the Nominal Frequency and Nominal Performance: Nominal Frequency = Max non-turbo ratio * cpu_bus_frequency Nominal Performance = Max non-turn ratio * cpu scaling factor CPU scaling factor varies in the hybrid core environment. So, the generated ACPI code updates Nominal Performance based on the CPU's scaling factor. TEST=Verified CPPCv3 package is getting created in the SSDT table.
