2020-05-19device: Add definitions for SoundWire specificationDuncan Laurie
This header implements structures to describe the properties defined in the SoundWire Discovery and Configuration Specification Version 1.0. By itself this just provides the property definitions, it is then used by the code that generates ACPI device properties and by the controller and codec drivers. A new header for MIPI vendor/device IDs is also added, with the MIPI Alliance board members added by default. This will be used in the same way as pci_ids.h to track devices added to coreboot.

2020-05-13lib/spd_cache: add spd_cache common codeJamie Chen
This patch adds some spd_cache functions. They are for implementing the spd_cache. It's for reducing the SPD fetch time when device uses SODIMMs. The MRC cache also includes SPD data, but there is no public header file available to decode the struct of MRC. So SPD cache is another solution.

2020-05-12device: Enable resource allocation above 4G boundaryFurquan Shaikh
This change adds support for allocating resources above the 4G boundary by making use of memranges for resource windows enabled in the previous CL. It adds a new resource flag IORESOURCE_ABOVE_4G which is used in the following ways: a) Downstream device resources can set this flag to indicate that they would like to have their resource allocation above the 4G boundary. These semantics will have to be enabled in the drivers managing the devices. It can also be extended to be enabled via devicetree. This flag is automatically propagated by the resource allocator from downstream devices to the upstream bridges in pass 1. It is done to ensure that the resource allocator has a global view of downstream requirements during pass 2 at domain level. b) Bridges have a single resource window for each of mem and prefmem resource types. Thus, if any downstream resource of the bridge requests allocation above 4G boundary, all the other downstream resources of the same type under the bridge will be allocated above 4G boundary. c) During pass 2, resource allocator at domain level splits IORESOURCE_MEM into two different memory ranges -- one for the window below 4G and other above 4G. Resource allocation happens separately for each of these windows. d) At the bridge level, there is no extra logic required since the resource will live entirely above or below the 4G boundary. Hence, all downstream devices of any bridge will fall within the window allocated to the bridge resource. To handle this case separately from that of domain, initializing of memranges for a bridge is done differently than the domain. Limitation: Resources of a given type at the bridge or downstream devices cannot live both above and below 4G boundary. Thus, if a bridge has some downstream resources requesting allocation for a given type above 4G boundary and other resources of the same type requesting allocation below 4G boundary, then all these resources of the same type get allocated above 4G boundary. BUG=b:149186922 TEST=Verified that resources get allocated above the 4G boundary correctly on volteer.

2020-04-29arch/x86: Implement RESET_VECTOR_IN_RAMFelix Held
Add support for devices with the reset vector pointing into DRAM. This is a specific implementation that assumes a paradigm of AMD Family 17h (a.k.a. "Zen"). Until the first ljmpl for protected mode, the core's state appears to software like other designs, and then the actual physical addressing becomes recognizable. These systems cannot implement cache-as-RAM as in more traditional x86 products. Therefore instead of reusing CAR names and variables, a substitute called "earlyram" is introduced. This change makes adjustments to CAR-aware files accordingly. Enable NO_XIP_EARLY_STAGES. The first stage is already in DRAM, and running subsequent stages as XIP in the boot device would reduce performance. Finally, add a new early_ram.ld linker file.

2020-04-28security/lockdown: Write-protect WP_ROPatrick Rudolph
Allow to write protect only the WP_RO region in case of enabled VBOOT. One can either lock the boot device in VERSTAGE early if VBOOT is enabled, or late in RAMSTAGE. Both options have their downsides as explained below. Lock early if you don't trust the code that's stored in the writeable flash partition. This prevents write-protecting the MRC cache, which is written in ramstage. In case the contents of the MRC cache are corrupted this can lead to system instability or trigger unwanted code flows inside the firmware. Lock late if you trust the code that's stored in the writeable flash partition. This allows write-protecting the MRC cache, but if a vulnerability is found in the code of the writeable partition an attacker might be able to overwrite the whole flash as it hasn't been locked yet.

2020-04-23rules.h: Rename ENV_VERSTAGE to ENV_SEPARATE_VERSTAGEJulius Werner
When CONFIG_SEPARATE_VERSTAGE=n, all verstage code gets linked into the appropriate calling stage (bootblock or romstage). This means that ENV_VERSTAGE is actually 0, and instead ENV_BOOTBLOCK or ENV_ROMSTAGE are 1. This keeps tripping up people who are just trying to write a simple "are we in verstage (i.e. wherever the vboot init logic runs)" check, e.g. for TPM init functions which may run in "verstage" or ramstage depending on whether vboot is enabled. Those checks will not work as intended for CONFIG_SEPARATE_VERSTAGE=n. This patch renames ENV_VERSTAGE to ENV_SEPARATE_VERSTAGE to try to clarify that this macro can really only be used to check whether code is running in a *separate* verstage, and clue people in that they may need to cover the linked-in verstage case as well.

2020-03-31security/vboot: Decouple measured boot from verified bootBill XIE
Currently, those who want to use measured boot implemented within vboot should enable verified boot first, along with sections such as GBB and RW slots defined with manually written fmd files, even if they do not actually want to verify anything. As discussed in CB:34977, measured boot should be decoupled from verified boot and make them two fully independent options. Crypto routines necessary for measurement could be reused, and TPM and CRTM init should be done somewhere other than vboot_logic_executed() if verified boot is not enabled. In this revision, only TCPA log is initialized during bootblock. Before TPM gets set up, digests are not measured into tpm immediately, but cached in TCPA log, and measured into determined PCRs right after TPM is up. This change allows those who do not want to use the verified boot scheme implemented by vboot as well as its requirement of a more complex partition scheme designed for chromeos to make use of the measured boot functionality implemented within vboot library to measure the boot process. TODO: Measure MRC Cache somewhere, as MRC Cache has never resided in CBFS any more, so it cannot be covered by tspi_measure_cbfs_hook().

This change updates the align attribute of memranges to be represented as log2 of the required alignment. This makes it consistent with how alignment is stored in struct resource as well. Additionally, since memranges only allow power of 2 alignments, this change allows getting rid of checks at runtime and hence failure cases for non-power of 2 alignments. This change also updates the type of align to be unsigned char.

2020-03-25create stdio.h and stdarg.h for {,v}snprintfJoel Kitching
Sometimes coreboot needs to compile external code (e.g. vboot_reference) using its own set of system header files. When these headers don't line up with C Standard Library, it causes problems. Create stdio.h and stdarg.h header files. Relocate snprintf into stdio.h and vsnprintf into stdarg.h from string.h. Chain include these header files from string.h, since coreboot doesn't care so much about the legacy POSIX location of these functions. Also move va_* definitions from vtxprintf.h into stdarg.h where they belong (in POSIX). Just use our own definitions regardless of GCC or LLVM. Add string.h header to a few C files which should have had it in the first place.

2020-02-08Add configurable ramstage support for minimal PCI scanningRonald G. Minnich
This CL has changes that allow us to enable a configurable ramstage, and one change that allows us to minimize PCI scanning. Minimal scanning is a frequently requested feature. To enable it, we add two new variables to src/Kconfig CONFIGURABLE_RAMSTAGE is the overall variable controlling other options for minimizing the ramstage. MINIMAL_PCI_SCANNING is how we indicate we wish to enable minimal PCI scanning. Some devices must be scanned in all cases, such as 0:0.0. To indicate which devices we must scan, we add a new mandatory keyword to sconfig It is used in place of on, off, or hidden, and indicates a device is enabled and mandatory. Mandatory devices are always scanned. When MINIMAL_PCI_SCANNING is enabled, ONLY mandatory devices are scanned. We further add support in src/device/pci_device.c to manage both MINIMAL_PCI_SCANNING and mandatory devices. Finally, to show how this works in practice, we add mandatory keywords to 3 devices on the qemu-q35. TEST= 1. This is tested and working on the qemu-q35 target. 2.

2020-02-05security/intel/stm: Add STM supportEugene Myers
This update is a combination of all four of the patches so that the commit can be done without breaking parts of coreboot. This possible breakage is because of the cross-dependencies between the original separate patches would cause failure because of data structure changes. security/intel/stm This directory contains the functions that check and move the STM to the MSEG, create its page tables, and create the BIOS resource list. The STM page tables is a six page region located in the MSEG and are pointed to by the CR3 Offset field in the MSEG header. The initial page tables will identity map all memory between 0-4G. The STM starts in IA32e mode, which requires page tables to exist at startup. The BIOS resource list defines the resources that the SMI Handler is allowed to access. This includes the SMM memory area where the SMI handler resides and other resources such as I/O devices. The STM uses the BIOS resource list to restrict the SMI handler's accesses. The BIOS resource list is currently located in the same area as the SMI handler. This location is shown in the comment section before smm_load_module in smm_module_loader.c Note: The files within security/intel/stm come directly from their Tianocore counterparts. Unnecessary code has been removed and the remaining code has been converted to meet coreboot coding requirements.

2020-02-05pciexp: Add support for allocating PCI express hotplug resourcesJeremy Soller
This change adds support for allocating resources for PCI express hotplug bridges when PCIEXP_HOTPLUG is selected. By default, this will add 32 PCI subordinate numbers (buses), 256 MiB of prefetchable memory, 8 MiB of non-prefetchable memory, and 8 KiB of I/O space to any device with the PCI_EXP_SLTCAP_HPC bit set in the PCI_EXP_SLTCAP register, which indicates hot-plugging capability. The resource allocation is configurable, please see the PCIEXP_HOTPLUG_* variables in src/device/Kconfig. In order to support the allocation of hotplugged PCI buses, a new field is added to struct device called hotplug_buses. This is defaulted to zero, but when set, it adds the hotplug_buses value to the subordinate value of the PCI bridge. This allows devices to be plugged in and unplugged after boot. This code was tested on the System76 Darter Pro (darp6). Before this change, there are not enough resources allocated to the Thunderbolt PCI bridge to allow plugging in new devices after boot. This can be worked around in the Linux kernel by passing a boot param such as: pci=assign-busses,hpbussize=32,realloc This change makes it possible to use Thunderbolt hotplugging without kernel parameters, and attempts to match closely what our motherboard manufacturer's firmware does by default.

In order to pack space as closely as possible the previous 32-bit id and mask were split into 2 16-bit ids and masks. On Chrome OS build of Aleena there's a savings of >2.21KiB in each of verstage, romstage, and ramstage.

2020-01-28commonlib: Add commonlib/bsdJulius Werner
This patch creates a new commonlib/bsd subdirectory with a similar purpose to the existing commonlib, with the difference that all files under this subdirectory shall be licensed under the BSD-3-Clause license (or compatible permissive license). The goal is to allow more code to be shared with libpayload in the future. Initially, I'm going to move a few files there that have already been BSD-licensed in the existing commonlib. I am also exracting most contents of the often-needed <commonlib/helpers.h> as long as they have either been written by me (and are hereby relicensed) or have an existing equivalent in BSD-licensed libpayload code. I am also relicensing <commonlib/compression.h> (written by me) and <commonlib/compiler.h> (same stuff exists in libpayload). Finally, I am extracting the cb_err error code definitions from <types.h> into a new BSD-licensed header so that future commonlib/bsd code can build upon a common set of error values. I am making the assumption here that the enum constants and the half-sentence fragments of documentation next to them by themselves do not meet the threshold of copyrightability.

2020-01-18cbfs: Remove locator conceptJulius Werner
When vboot was first integrated into CBFS it was still part of Google vendorcode. So to not directly tie custom vendorcode into the core CBFS library, the concept of cbfs_locator was introduced to decouple core code from an arbitrary amount of platform-specific implementations that want to decide where the CBFS can be found. Nowadays vboot is a core coreboot feature itself, and the locator concept isn't used by anything else anymore. This patch simplifies the code by removing it and just calling vboot from the CBFS library directly. That should make it easier to more closely integrate vboot into CBFS in the future.

2020-01-17drivers/spi/spi_flash: organize spi flash by sector topologyAaron Durbin
By grouping the spi flash parts by their {vendor, sector topology} tuple one can use a common probe function for looking up the part instead of having per-vendor probe functions. Additionally, by grouping by the command set one can save more space as well. SST is the exception that requires after_probe() function to unlock the parts. 2KiB of savings in each of verstage, romstage, and ramstage on Aleena Chrome OS Build.

2020-01-17drivers/spi/spi_flash: introduce common spi_flash_part_id objectAaron Durbin
To further drive to a common approach for describing the spi flash parts in the drivers add spi_flash_part_id object. All the drivers are updated to utilize the new object. Additionally, the driver_private is also not needed in the spi_flash object. A Chrome OS build of Aleena provides 960 byte saving of text. A subsequent patch will save more memory.

2020-01-16drivers/spi/spi_flash: separate out protection opsAaron Durbin
Put the write protection into its own object. This allows for easier future reuse of objects in future consolidation patches. It's also possible to eliminate the code implmementing these in the future if the platform doesn't require it. For now leave current behavior as-is. The names of the callbacks were shortened as they are now in the spi_flash_protection_ops object which is a new field in the spi_flash object.
