2020-12-10drivers/genesyslogic/gl9755: Adjust L1 exit latency to enable ASPMDuncan Laurie
Configure the CFG2 register to set the latency to <64us in order to ensure the L1 exit latency is consistent across devices and that L1 ASPM is always enabled. This moves the setup code from device init to device enable so it executes before coreboot does ASPM configuration, and removes the call to pci_dev_init() as that is just for VGA Option ROMs. BUG=b:173207454 TEST=Verify the device and link capability and control for L1: DevCap: Latency L1 <64us LnkCap: Latency L1 <64us LnkCtl: ASPM L1 Enabled Signed-off-by: Duncan Laurie <dlaurie@google.com> Change-Id: Ie2b85a6697f164fbe4f84d8cd5acb2b5911ca7a9 Reviewed-on: https://review.coreboot.org/c/coreboot/+/47682 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org>

2020-12-08coreboot tables: Add SPI flash memory map windows to coreboot tablesFurquan Shaikh
This change adds details about the memory map windows to translate addresses between SPI flash space and host address space to coreboot tables. 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). Test: Supermicro X11SSM-F builds and boots fine with custom FSP FD set.

2020-11-16drivers/i2c/dw: Check for TX_ABORT in transferKangheui Won
When the host sends data in i2c bus, device might not send ACK. It means that data is not processed on the device side, but for now we don't check for that condition thus wait for the response which will not come. Designware i2c detect such situation and set TX_ABORT bit. Checking for the bit will enable other layers to immediately retry rather than wait-timeout-retry cycle.

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.

2020-11-09drivers/usb/acpi: Add support for privacy_gpioRicardo Ribalda
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.

Thus, with this change, CNVi entry in devicetree can be changed from: ``` chip drivers/wifi/generic register "wake" = "xxyyzz" device pci xx.y on end # CNVi PCI device end ``` to: ``` device pci xx.y on chip drivers/wifi/generic register "wake" = "xxyyzz" device generic 0 on end # Dummy CNVi device end end # CNVi PCI device ``` The helper functions for ACPI/SMBIOS generation are also accordingly updated to include _pcie_ and _cnvi_ in the function name.

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.
