2021-01-07arch/x86: Move prologue to .init sectionKyösti Mälkki
For arch/x86 the realmode part has to be located within the same 64 KiB as the reset vector. Some older intel platforms also require 4 KiB alignment for _start16bit. To enforce the above, and to separate required parts of .text without matching *(.text.*) rules in linker scripts, tag the pre-C environment assembly code with section .init directive. Description of .init section for ELF: This section holds executable instructions that contribute to the process initialization code. When a program starts to run, the system arranges to execute the code in this section before calling the main program entry point (called main for C programs).

2021-01-04drivers/vpd: Add VPD region to default FMAP when selectedMatt DeVillier
Currently, use of the VPD driver to read VPD tables from flash requires the use of a custom FMAP with one or more VPD regions.

This is useful for payloads to setup the translation using the decode windows already known to coreboot. Until now, there was a single decode window at the top of 4G used by all x86 platforms. However, going forward, platforms might support more decode windows and hence in order to avoid duplication in payloads this information is filled in coreboot tables. `lb_spi_flash()` is updated to fill in the details about these windows by making a call to `spi_flash_get_mmap_windows()` which is implemented by the driver providing the boot media mapping device.

2020-12-08drivers/i2c/tpm: Unconditionally allow I2C TPM ACPI nodeJes Klinke
DRIVER_I2C_TPM_ACPI is used to enable the "driver" needed for coreboot to present a TPM node in the devicetree. It would usually only do so, if coreboot itself is communicating with the TPM via I2C (I2C_TPM). However, technically, there is no dependency. In order to not show the ACPI option in menuconfig if the board is not using I2C, a dependency was declared in Kconfig. However, the same can be achieved without making it an error to manually declare DRIVER_I2C_TPM_ACPI without I2C_TPM. For Volteer, we have just such a need, since it has two "sub-variants" sharing the same overridetree.cb, one having SPI TPM and another having I2C TPM. The former will have a disabled ACPI node representing the I2C TPM, while its Kconfig is such that coreboot itself does not have I2C TPM support. In order to export even a disabled ACPI node representing the I2C connected TPM, coreboot needs DRIVER_I2C_TPM_ACPI. Hence, that will have to be enabled in a case where coreboot does not have I2C_TPM (for one of the two sub-variants, namely volteer2).

2020-12-02cbfs: Simplify load/map API names, remove type argumentsJulius Werner
This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file() to cbfs_map() and cbfs_load() respectively. This is supposed to be the start of a new, better organized CBFS API where the most common operations have the most simple and straight-forward names. Less commonly used variants of these operations (e.g. cbfs_ro_load() or cbfs_region_load()) can be introduced later. It seems unnecessary to keep carrying around "boot" in the names of most CBFS APIs if the vast majority of accesses go to the boot CBFS (instead, more unusual operations should have longer names that describe how they diverge from the common ones). cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly reap mappings when desired. A few new cbfs_unmap() calls are added to generic code where it makes sense, but it seems unnecessary to introduce this everywhere in platform or architecture specific code where the boot medium is known to be memory-mapped anyway. In fact, even for non-memory-mapped platforms, sometimes leaking a mapping to the CBFS cache is a much cleaner solution than jumping through hoops to provide some other storage for some long-lived file object, and it shouldn't be outright forbidden when it makes sense. Additionally, remove the type arguments from these function signatures. The goal is to eventually remove type arguments for lookup from the whole CBFS API. Filenames already uniquely identify CBFS files. The type field is just informational, and there should be APIs to allow callers to check it when desired, but it's not clear what we gain from forcing this as a parameter into every single CBFS access when the vast majority of the time it provides no additional value and is just clutter.

2020-11-26drivers/intel/fsp2_0: introduce possibility of using a full FD binaryMichael Niewöhner
Currently, setting a custom FSP binary is only possible by using split FSP-T/M/S FD files. This change introduces the possibility to pass a combined FD file (the "standard" FSP format). This is done by adding a new boolean Kconfig FSP_FULL_FD, specifying that the FSP is a single FD file instead of split FSP-T/M/S FD files, and making FSP_FD_PATH user-visible when the option is chosen. In this case, the other options for split files get hidden. When the user chooses to use a full FD file instead of the split ones, the FD file gets split during build, just like it is done when selecting the Github FSP repo (FSP_USE_REPO).

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.

This change splits `wifi_generic_fill_ssdt()` into following two functions: 1. `wifi_ssdt_write_device()`: This function writes the device, its address, _UID and _DDN. 2. `wifi_ssdt_write_properties()`: This function writes the properties for WiFi device like _PRW, regulatory domain and SAR. This split is done so that the device write can be skipped for CNVi devices in follow-up CLs. It will allow the SoC controller representation for CNVi PCI device to be consistent with other internal PCI devices in the device tree i.e. not requiring a chip driver for the PCI device. Because of this change, _PRW and SAR will be seen in a separate block in SSDT disassembly, but it does not result in any functional change.

2020-10-22drivers/smmstore: Implement SMMSTORE version 2Patrick Rudolph
SMMSTORE version 2 is a complete redesign of the current driver. It is not backwards-compatible with version 1, and only one version can be used at a time. Key features: * Uses a fixed communication buffer instead of writing to arbitrary memory addresses provided by untrusted ring0 code. * Gives the caller full control over the used data format. * Splits the store into smaller chunks to allow fault tolerant updates. * Doesn't provide feedback about the actual read/written bytes, just returns error or success in registers. * Returns an error if the requested operation would overflow the communication buffer. Separate the SMMSTORE into 64 KiB blocks that can individually be read/written/erased. To be used by payloads that implement a FaultTolerant Variable store like TianoCore. The implementation has been tested against EDK2 master. An example EDK2 implementation can be found here: https://github.com/9elements/edk2-1/commit/eb1127744a3a5d5c8ac4e8eb76f07e79c736dbe2 Change-Id: I25e49d184135710f3e6dd1ad3bed95de950fe057 Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com> Signed-off-by: Christian Walter <christian.walter@9elements.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40520 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Michał Żygowski <michal.zygowski@3mdeb.com> Reviewed-by: Matt DeVillier <matt.devillier@gmail.com>

This change limits the scope of `wifi_generic_fill_ssdt()` and `wifi_generic_acpi_name()` to generic.c since they are not used outside of this file anymore. Also, since there is no need to split SSDT generator into two separate functions, `wifi_generic_fill_ssdt_generator()` is dropped and `.acpi_fill_ssdt` directly points to `wifi_generic_fill_ssdt()`.

2020-10-13drivers/{intel/wifi,wifi/generic}: Drop separate Intel WiFi driverFurquan Shaikh
Currently, drivers/intel/wifi is a PCI driver (provides `struct pci_driver`) as well as a chip driver (provides `struct chip_operations`). However, there is no need for a separate chip driver for the WiFi device since drivers/wifi/generic already provides one. Having two separate chip drivers makes it difficult to multi-source WiFi devices and share the same firmware target without having to add a probe property for each of these devices. This is unnecessary since the WiFi driver in coreboot is primarily responsible for: 1. PCI resource allocation 2. ACPI SSDT node generation to expose wake property and SAR tables 3. SMBIOS table generation For the most part, coreboot can perform the above operations without really caring about the specifics of which WiFi device is being used by the mainboard. Thus, this change drops the driver for intel/wifi and moves the PCI driver support required for Intel WiFi chips into drivers/wifi/generic. The PCI driver is retained for backward compatibility with boards that never utilized the chip driver to support Intel WiFi device. For these devices, the PCI driver helps perform the same operations as above (except exposing the wake property) by utilizing the same `wifi_generic_ops`. This change also moves DRIVERS_INTEL_WIFI config to wifi/generic/Kconfig.

2020-10-13drivers/{wifi/generic,intel/wifi}: Drop dependency on HAVE_ACPI_TABLESFurquan Shaikh
This change drops the dependency of DRIVERS_WIFI_GENERIC on HAVE_ACPI_TABLES as the driver provides operations other than the ACPI support for WiFi devices. Since the dependency is now dropped, ACPI operations in generic.c are guarded by CONFIG(HAVE_ACPI_TABLES).

2020-10-11drivers/i2c/nct7802y: Configure remote diodes and local sensorMaxim Polyakov
The patch allows to configure sensors with a remote diode connected and a on-chip local temperature sensor from the devicetree for the board that uses this HWM. According to the documentation [1], this is done by setting the corresponding bits in the Mode Selection Register (22h). It is necessary for some Intel processors (Apollo Lake SoC) that do not support PECI and the CPU temperature is taken from the thermistor. TEST = After loading the nct7802 module on the Kontron mAL-10 [2] with Linux OS, we can see configuration of the HWM with one sensor in the thermistor mode: user@user-apl:~$ sensors coretemp-isa-0000 Adapter: ISA adapter Package id 0: +41.0°C (high = +110.0°C, crit = +110.0°C) Core 0: +40.0°C (high = +110.0°C, crit = +110.0°C) Core 1: +40.0°C (high = +110.0°C, crit = +110.0°C) Core 2: +41.0°C (high = +110.0°C, crit = +110.0°C) Core 3: +41.0°C (high = +110.0°C, crit = +110.0°C) nct7802-i2c-0-2e Adapter: SMBus CMI adapter cmi in0: +3.35 V (min = +0.00 V, max = +4.09 V) in1: +1.92 V in3: +1.21 V (min = +0.00 V, max = +2.05 V) in4: +1.68 V (min = +0.00 V, max = +2.05 V) fan1: 0 RPM (min = 0 RPM) fan2: 868 RPM (min = 0 RPM) fan3: 0 RPM (min = 0 RPM) temp1: +42.5°C (low = +0.0°C, high = +85.0°C) (crit = +100.0°C) sensor = thermistor temp4: +44.0°C (low = +0.0°C, high = +85.0°C) (crit = +100.0°C) temp6: +0.0°C [1] page 30, section 7.2.32, Nuvoton Hardware Monitoring IC NCT7802Y with PECI 3.0 interface, datasheet, revision 1.2, february 2012 [2] https://review.coreboot.org/c/coreboot/+/39133 Change-Id: I28cc4e5cae76cf0bcdad26a50ee6cd43a201d31e Signed-off-by: Maxim Polyakov <max.senia.poliak@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/39766 Reviewed-by: Werner Zeh <werner.zeh@siemens.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2020-10-11drivers/wifi: Drop maxsleep parameter from chip configFurquan Shaikh
This change drops maxsleep parameter from chip config and instead hardcodes the deepest sleep state from which the WiFi device can wake the system up from to SLP_TYP_S3. This is similar to how other device drivers in coreboot report _PRW property in ACPI. It relieves the users from adding another register attribute to devicetree since all mainboards configure the same value. If this changes in the future, it should be easy to bring the maxsleep config parameter back.
