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. HAS_RECOVERY_MRC_CACHE, only invalidate if retrain switch is set BUG=b:150502246 BRANCH=None TEST=1. run dut-control power_state:rec_force_mrc twice on lazor ensure that memory retraining happens both times run dut-control power_state:rec twice on lazor ensure that memory retraining happens only first time 2. remove HAS_RECOVERY_MRC_CACHE from lazor Kconfig boot twice to ensure caching of memory training occurred on each boot.

2020-11-10drivers/wifi: Check device is of type PCI before checking vendor IDFurquan Shaikh
CB:46865 ("mb, soc/intel: Reorganize CNVi device entries in devicetree") reorganized the devicetree entries to make the representation of CNVi device consistent with other internal PCI devices. Since a dummy generic device is added for the CNVi device, `emit_sar_acpi_structures()` needs to first check if the device is PCI before checking the vendor ID. This ensures that SAR table generation is skipped only for PCIe devices with non-Intel vendor IDs and not for the dummy generic device.

Some devices, such as cameras, can implement a physical switch to disable the input on demand. Think of it like the typical privacy sticker on the notebooks, but more elegant. In order to notify the system about the status this feature, a GPIO is typically used. The map between a GPIO and the feature is done via ACPI, the same way as the reset_gpio works. This patch implements an extra field for the described privacy gpio. This gpio does not require any extra handling from the power management.

2020-11-02drivers/wifi/generic: Split wifi_generic_fill_ssdt into two functionsFurquan Shaikh
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>

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.
