2020-11-27soc/intel/jasperlake: Enable VT-d and generate DMAR TableMeera Ravindranath
Update UPDs required for the creation of DMAR table. By default coreboot was not generating DMAR table for IOMMU which was resulting in below error message in kernel: DMAR: [Firmware Bug]: No DRHD structure found in DMAR table DMAR: No DMAR devices found These changes will publish DMAR table through ACPI and will not result in the above error. BUG=b:170261791 BRANCH=dedede TEST=Build Dedede, boot to kernel and check dmesg if DMAR table exists.

2020-11-24soc/intel/xeon_sp: Enable SMI handlerRocky Phagura
SMI handler was not installed for Xeon_sp platforms. This enables SMM relocation and SMI handling. TESTED: - SMRR are correctly set - The save state revision is correct (0x00030101) - SMI's are properly generated and handled - SMM MSR save state are not supported, so relocate SMM on all cores in series - Verified on OCP/Deltalake mainboard. NOTE: - Code for accessing a CPU save state is not working for SMMLOADERV2, so some SMM features like GSMI, SMMSTORE, updating the ACPI GNVS pointer are not supported. - This hooks up to some soc/intel/common like TCO and ACPI GNVS. GNVS is broken and needs to be fixed separately. It is unknown if TCO is supported. This might require a cleanup in the future.

2020-11-20soc/intel/common: Add PCIe Runtime D3 driver for ACPIDuncan Laurie
This driver is for devices attached to a PCIe root port that support Runtime D3. It creates the necessary PowerResource in the root port to provide _ON/_OFF methods for which will turn off power and clocks to the device when it is in the D3cold state. The mainboard declares the driver in devicetree and provides the GPIOs that control power/reset for the device attached to the root port and the SRCCLK pin used for the PMC IPC mailbox to enable/disable the clock. An additional device property is created for storage devices if it matches the PCI storage class which is used to indicate that the storage device should use D3 for power savings.

Replace the two obsolete LPID implementations with the new PEPD device. The PEPD device gets included in the plaforms' `southbridge.asl`, since it is required to load the `intel_pmc_core` module in Linux, which checks for the _HID. (See CB:46469 for more info on that.) There is no harm for mainboards not supporting S0ix, because the _DSM function won't be called with the LPS0 UUID on such boards.

2020-11-20soc/intel/common/acpi: work around Windows crash on S0ix-enabled boardsMichael Niewöhner
Windows does not comply with the Low Power Idle S0 specification and crashes with an `INTERNAL_POWER_ERROR` bluescreen when function 1, does not return at least one device constraint, even when function 1 is announced as being not available by the enum function. Returning an empty package does not work. At least the following Windows versions were verified to be affected: - Windows 8.1 x64, release 6.3.9600 - Windoes 10 x64, version 1809, build 17763.379 - Windows 10 x64, version 1903, build 18362.53 - Windows 10 x64, version 2004, build 19041.508 - Windows 10 x64, version 20H2 / 2009, build 19042.450 To make Windows work on S0ix-enabled boards, return a dummy constraint package with a disabled dummy device. Since the device constraints are only used for debugging low power states in Linux and probably also in Windows, there shouldn't be any negative effect to S0ix. Real device constraint entries could be added at a later point, if needed. Note: to fully prevent the BSOD mentioned above the LPIT table is required on Windows, too. The patch for this is WIP, see CB:32350. If you want to test this, you need to applie the whole ACPI patch series including the hacky LPIT test implementation from CB:47242: https://review.coreboot.org/q/topic:%22low_power_idle_fix%22 Test: no bluescreen anymore on Clevo L140CU on all Windows versions listed above and S0ix gets detected in `powercfg -a`.

2020-11-13mrc_cache: Move code for triggering memory training into mrc_cacheShelley Chen
Currently the decision of whether or not to use mrc_cache in recovery mode is made within the individual platforms' drivers (ie: fsp2.0, fsp1.1, etc.). As this is not platform specific, but uses common vboot infrastructure, the code can be unified and moved into mrc_cache. The conditions are as follows: 1. If HAS_RECOVERY_MRC_CACHE, use mrc_cache data (unless retrain switch is true) 2. If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_BOOTBLOCK, this means that memory training will occur after verified boot, meaning that mrc_cache will be filled with data from executing RW code. So in this case, we never want to use the training data in the mrc_cache for recovery mode. 3. If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_ROMSTAGE, this means that memory training happens before verfied boot, meaning that the mrc_cache data is generated by RO code, so it is safe to use for a recovery boot. 4. Any platform that does not use vboot should be unaffected. Additionally, we have removed the MRC_CLEAR_NORMAL_CACHE_ON_RECOVERY_RETRAIN config because the mrc_cache driver takes care of invalidating the mrc_cache data for normal mode. If the platform: 1. !HAS_RECOVERY_MRC_CACHE, always invalidate mrc_cache data 2.

Currently, the ACPI PM timer state gets set in devicetree by the option PmTimerDisabled. However, it is not board design dependent. Thus, add a user-selectable Kconfig option. Disabling the PM ACPI Timer is only valid when PM Timer emulation is supported and is only possible, when there is a hardware PM Timer (APL does not have one for example). SoCs, where the hardware PM Timer can be disabled must select `PM_ACPI_TIMER_OPTIONAL`. This new Kconfig gets used in the follow-up commits of this series.

2020-11-09soc/intel/jasperlake: Correct GPIO pad sequence for community pad groupMaulik V Vaghela
In gpio.c file, we have community group array for each comm, representing gpio groups within that community. Like there might be group H,D, VGPIO and C within community 1. Community also may have some reserved gpio and we also define those in an array which indicates OS can't use those GPIO (through PAD_BASE_NONE) Now when we define reserved pads in the middle of actual community pads, it creates an issue while calculating an offset for GPIO host own pad register. This is because function actually checks current gpio index (lets say vgpio_39 in our case) and tries to get group index from an array which we have defined. If we have defined reserved gpios in between 2 communities, index calculated will also account for reserved GPIO and register offset calculation will move to next set of register (offset 0xC instead of offset 0x8). Because of this coreboot won't configure HOST_OWN_PAD register correctly and driver will not be able to get non-SMI interrupts for related gpio. Align pad group as per EDS and pin-ctrl driver in linux kernel. Reference: DOC#618876 (EDS volume 2) BUG=None BRANCH=None TEST=VGPIO community index is correctly calculated.
