2021-11-10Rename ECAM-specific MMCONF KconfigsShelley Chen
Currently, the MMCONF Kconfigs only support the Enhanced Configuration Access mechanism (ECAM) method for accessing the PCI config address space. Some platforms have a different way of mapping the PCI config space to memory. This patch renames the following configs to make it clear that these configs are ECAM-specific: - NO_MMCONF_SUPPORT --> NO_ECAM_MMCONF_SUPPORT - MMCONF_SUPPORT --> ECAM_MMCONF_SUPPORT - MMCONF_BASE_ADDRESS --> ECAM_MMCONF_BASE_ADDRESS - MMCONF_BUS_NUMBER --> ECAM_MMCONF_BUS_NUMBER - MMCONF_LENGTH --> ECAM_MMCONF_LENGTH Please refer to CB:57861 "Proposed coreboot Changes" for more details.

2021-11-08soc/intel: drop Kconfig `PM_ACPI_TIMER_OPTIONAL`Michael Niewöhner
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.

2021-10-26cpu/x86: Introduce and use `CPU_X86_LAPIC`Felix Held
With using a Kconfig option to add the x86 LAPIC support code to the build, there's no need for adding the corresponding directory to subdirs in the CPU/SoC Makefile. 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. So for now the default value of CPU_X86_LAPIC is chosen as y which gets overridden to n in the Kconfig of the two SoCs mentioned above.

2021-10-25cpu,soc/x86: always include cpu/x86/mtrr on x86 CPUs/SoCsFelix Held
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.

2021-10-22cpu/x86/mp_init: move printing of failure message into mp_init_with_smmFelix Held
Each CPU/SoC checks the return value of the mp_init_with_smm and prints the same error message if it wasn't successful, so move this check and printk to mp_init_with_smm. For this the original mp_init_with_smm function gets renamed to do_mp_init_with_smm and a new mp_init_with_smm function is created which then calls do_mp_init_with_smm, prints the error if it didn't return CB_SUCCESS and passes the return value of do_mp_init_with_smm to its caller. Since no CPU/SoC code handles a mp_init_with_smm failure apart from printing a message, also add a comment at the mp_init_with_smm call sites that the code might want to handle a failure.

2021-09-20soc/intel/icelake: 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).

2021-03-27soc/intel: Rename and move MISCCFG_GPIO_PM_CONFIG_BITS definition to soc/gpio.hSubrata Banik
Lists of changes: 1. Rename MISCCFG_ENABLE_GPIO_PM_CONFIG -> MISCCFG_GPIO_PM_CONFIG_BITS 2. Move MISCCFG_GPIO_PM_CONFIG_BITS definition from intelblock/gpio.h to soc/gpio.h. Refer to detailed description below to understand the motivation behind this change. An advanced GPIO PM capabilities has been introduced since CNP PCH, refer to 'include/intelblock/gpio.h' for detailed GPIO PM bit definitions. Now with TGP PCH, additional bits are defined in the MISCCFG register for GPIO PM control. This results in different SoCs supporting different number of bits. The bits defined in earlier platforms (CNL, CML, ICL) are present on TGL, JSL and ADL too. Hence, refactor the common GPIO code to keep the bit definitions in intelblock/gpio.h, but the definition of MISCCFG_GPIO_PM_CONFIG_BITS is moved to soc/gpio.h so that each SoC can provide this as per hardware support. TEST=On ADL, TGL and JSL platform. Without this CL : GPIO COMM 0 MISCCFG:0xC0 (Bit 6 and 7 enable) With this CL : GPIO COMM 0 MISCCFG: 0x00 (Bit 6 and 7 disable) Change-Id: Ie027cbd7b99b39752941384339a34f8995c10c94 Signed-off-by: Subrata Banik <subrata.banik@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/51767 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>

Backport commit 0cded1f116 (soc/intel/tigerlake: Add SMRR Locking support) to other client platforms. The SMRR MSRs are core-scoped on Skylake and Ice Lake, at least. Older platforms do not support SMRR locking, but now there's seven copies of the same file in the tree. A follow-up will deduplicate smmrelocate.c files into common CPU code. I cannot test Jasper Lake nor Elkhart Lake, but they should still work. As per documentation I do not have access to, Elkhart Lake seems to support SMRR locking. However, Jasper Lake documentation is unclear. Tested on Purism Librem Mini v1 (WHL-U i7-8565U), still boots and SMRR MSRs have the same value on all cores/threads (i7-8565U supports HT).

FSP_PEIM_TO_PEIM_INTERFACE is used for: * Auto-selecting FSP_USES_MP_SERVICES_PPI * Including src/drivers/intel/fsp2_0/ppi/Kconfig * Adding ppi to subdirs-y * Setting USE_INTEL_FSP_TO_CALL_COREBOOT_PUBLISH_MP_PPI to y and is selected by SoCs that want to enable MP PPI services. 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. TEST=Verified that timeless build for brya, volteer, icelake_rvp, elkhartlake_crb and waddledee shows no change in generated coreboot.rom Change-Id: I0664f09d85f5be372d19925d47034c76aeeef2ae Signed-off-by: Furquan Shaikh <furquan@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/50274 Reviewed-by: Aamir Bohra <aamir.bohra@intel.com> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-by: Subrata Banik <subrata.banik@intel.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

2021-01-31soc/intel/*: drop incomplete and unneeded check for DMI SRLOCKMichael Niewöhner
Before enabling IO decode ranges, current code checks if the DMI SRLOCK is set to prevent inconsistencies between LPC PCI cfg registers and LPC DMI registers, when the latter are locked. DMI SRLOCK only applies to PCHs with on-package DMI, but not to PCH-H, PCH-S and others with discrete PCH packages. So this check is at least incomplete. Further, the lock gets applied by FSP and gets reset on a warm reset. Thus, there is no case where the lock would be already set at the places where the DMI registers get written currently. Drop the checks for the reasons mentioned above.

This function uses the parameter dev to get a pointer to config structure for extracting the decode ranges configured by mainboard in device tree.

This change is being done in preparation to clean up the device tree/chip config access in early stages that allows for optimizing the inclusion of device tree elements in the early stages.
