2020-12-11fw_config: Use UNDEFINED_FW_CONFIG to mean unprovisionedTim Wawrzynczak
A mainboard might want to configure some things differently when a device is in an unprovisioned state. In the case when fw_config comes from the Chromium EC, an unprovisioned device will not have a FW_CONFIG tag in its CBI. This patch will set the fw_config value to UNDEFINED_FW_CONFIG in the case of an error retrieving the value, as well as adding a function, `fw_config_is_provisioned()` to indicate the provisioning status. BUG=none TEST=remove fw_config from chromium EC CBI, add code to mainboard to print return value of fw_config_is_provisioned() (`0`), add fw_config back to CBI, run same test and see `1`.

2020-12-10lib/edid_fill_fb: Support multiple framebuffersPatrick Rudolph
Currently it's not possible to add multiple graphics driver into one coreboot image. This patch series will fix this issue by providing a single API that multiple graphics driver can use. This is required for platforms that have two graphic cards, but different graphic drivers, like Intel and Aspeed on server platforms or Intel and Nvidia on consumer notebooks. The goals are to remove duplicated fill_fb_framebuffer(), to advertise multiple independent framebuffers in coreboot tables, and better runtime/build time graphic configuration options. Add an implementation in edid_fill_fb that supports registering multiple framebuffers, each with its own configuration. As the current code is only compiled for a single graphics driver there's no change in functionality.

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.

2020-12-08cbmem: Make cbmem_online() accurate on stages after romstageJulius Werner
cbmem_online() always returns 1 in stages after romstage. However, CBMEM isn't actually immediately available in those stages -- instead, it will only become available when cbmem_initialize() is called. That usually happens very early in the stage, but there are still small amounts of code running beforehand, so it is useful to reflect this distinction.

2020-12-03cbfs: Add verification for RO CBFS metadata hashJulius Werner
This patch adds the first stage of the new CONFIG_CBFS_VERIFICATION feature. It's not useful to end-users in this stage so it cannot be selected in menuconfig (and should not be used other than for development) yet. With this patch coreboot can verify the metadata hash of the RO CBFS when it starts booting, but it does not verify individual files yet. Likewise, verifying RW CBFSes with vboot is not yet supported. Verification is bootstrapped from a "metadata hash anchor" structure that is embedded in the bootblock code and marked by a unique magic number. This anchor contains both the CBFS metadata hash and a separate hash for the FMAP which is required to find the primary CBFS. Both are verified on first use in the bootblock (and halt the system on failure). The CONFIG_TOCTOU_SAFETY option is also added for illustrative purposes to show some paths that need to be different when full protection against TOCTOU (time-of-check vs. time-of-use) attacks is desired. For normal verification it is sufficient to check the FMAP and the CBFS metadata hash only once in the bootblock -- for TOCTOU verification we do the same, but we need to be extra careful that we do not re-read the FMAP or any CBFS metadata in later stages. This is mostly achieved by depending on the CBFS metadata cache and FMAP cache features, but we allow for one edge case in case the RW CBFS metadata cache overflows (which may happen during an RW update and could otherwise no longer be fixed because mcache size is defined by RO code). This code is added to demonstrate design intent but won't really matter until RW CBFS verification can be supported.

Looks like the option is generally not compatible with garbage collections. Nothing gets inlined, for example is_smp_boot() no longer evaluates to constant false and thus the symbols from secondary.S would need to be present for the build to pass even if we set SMP=n. Also the addresses of relocatable ramstage are currently not normalised on the logs, so util/genprof would be unable dress those.

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.

2020-12-02cbfs: Move more stuff into cbfs_boot_lookup()Julius Werner
cbfs_boot_locate() is supposed to be deprecated eventually, after slowly migrating all APIs to bypass it. That means common features (like RO-fallback or measurement) need to be moved to the new cbfs_boot_lookup(). Also export the function externally. Since it is a low-level API and most code should use the higher-level loading or mapping functions instead, put it into a new <cbfs_private.h> to raise the mental barrier for using this API (this will make more sense once cbfs_boot_locate() is removed from <cbfs.h>).

2020-11-21cbfs: Add metadata cacheJulius Werner
This patch adds a new CBFS "mcache" (metadata cache) -- a memory buffer that stores the headers of all CBFS files. Similar to the existing FMAP cache, this cache should reduce the amount of SPI accesses we need to do every boot: rather than having to re-read all CBFS headers from SPI flash every time we're looking for a file, we can just walk the same list in this in-memory copy and finally use it to directly access the flash at the right position for the file data. This patch adds the code to support the cache but doesn't enable it on any platform. The next one will turn it on by default.

2020-11-09cpu/x86/smm: Add a common save state handlingArthur Heymans
Currently coreboot has limited use for the SMM save state. Typically the only thing needed is to get or set a few registers and to know which CPU triggered the SMI (typically via an IO write). Abstracting away different SMM save states would allow to put some SMM functionality like the SMMSTORE entry in common places. To save place platforms can select different SMM save sate ops that should be implemented. For instance AMD platforms don't need Intel SMM save state handling. Some platforms can encounter CPUs with different save states, which the code then handles at runtime by comparing the SMM save state revision which is located at the same offset for all SMM save state types.

2020-11-03include/list.h: Add support for GCC9+Patrick Rudolph
When getting the address of a structure's member that is not on offset 0, GCC9+ assumes that the address can never be NULL. However the code relied on the fact that it can be NULL by letting the pointer intentionally overflow. Manually calculate the address using uintptr_t. This allows to gracefully terminate the list_for_each MACRO instead of crashing at the end of the list. Tested on qemu-system-arm: coreboot no longer crashed in the devicetree parser and is able to boot Linux 5.5.

This patch hooks coreboot up to the new commonlib/bsd CBFS implementation.

Future changes will migrate the higher level CBFS APIs one-by-one to use the new implementation directly (rather than translated into the results of the old one), at which point this will become more efficient.

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>

2020-10-16include/cpu/x86: introduce new helper for (un)setting MSRsMichael Niewöhner
msr_set_bit can only set single bits in MSRs and causes mixing of bit positions and bitmasks in the MSR header files. Thus, replace the helper by versions which can unset and set whole MSR bitmasks, just like the "and-or"-helper, but in the way commit 64a6b6c was done (inversion done in the helper). This helps keeping the MSR macros unified in bitmask style. In sum, the three helpers msr_set, msr_unset and msr_unset_and_set get added. The few uses of msr_set_bit have been replaced by the new version, while the used macros have been converted accordingly.
