2020-05-02acpi: Move ACPI table support out of arch/x86 (4/5)Furquan Shaikh
This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent. ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory. In order to make it easier to review, this change is being split into multiple CLs. This is change 4/5 which gets rid of the placeholder header files that were added to temporarily include acpi/ header files from arch/header files.

2020-05-02acpi: Move ACPI table support out of arch/x86 (1/5)Furquan Shaikh
This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent. ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory. In order to make it easier to review, this change is being split into multiple CLs. This is change 1/5 which moves .c files from arch/x86 to acpi/. The only acpi files that are still retained under arch/x86 are: a. acpi_s3.c: This doesn't really deal with ACPI tables. Also, there are some assumptions in there about SMM which will have to be resolved if this file needs to be moved to common code. b. acpi_bert_storage.c/bert_storage.h: This file is currently written specifically with x86 in mind. So, not moving the file for now. Motivation for this change: Not all stages on Picasso SoC are targeted for the same architecture. For example, verstage (if runs before bootblock) will be targeted for non-x86. This makes it difficult to add device tree to verstage which would be required to get to SoC configs from the tree. This is because the device tree on x86 platforms currently contains a lot of devices that require ACPI related enums and structs (like acpi_gpio, acpi_pld, acpi_dp and so on). Hence, this change removes all ACPI table support out of arch/x86.

2020-05-01arch/x86/acpi_device: Allow empty child referencesDuncan Laurie
Currently if a child table is created and added to a property list without adding any properties to that child it will generate an empty package. For example: struct acpi_dp *dsd = acpi_dp_new_table("_DSD"); struct acpi_dp *prop = acpi_dp_new_table("PROP"); acpi_dp_add_child(dsd, "dsd-prop", prop); acpi_dp_write(dsd); Results in an empty PROP package: Name (_DSD, Package (2) { ToUUID("dbb8e3e6-5886-4ba6-8795-1319f52a966b") Package (1) { Package (2) { "dsd-prop", "PROP" } } } Name (PROP, Package (0) { } Empty packages don't seem to be explicitly forbidden, but they don't serve a purpose with device properties. Instead, if packages without any properties or children are skipped then this empty package is not written and the added child property can refer to another property that is already defined. This allows creating property references to existing tables, which can save duplication and namespace collision issues with nested properties.

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. Because all stages run in DRAM, they can be linked with their .data and .bss as normal, i.e. they don't need to rely on storage available only at a fixed location like CAR systems. The primary purpose of the early_ram.ld is to provide consistent locations for PRERAM_CBMEM_CONSOLE, TIMESTAMP regions, etc. across stages until cbmem is brought online.

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().

According to the POSIX standard, %p is supposed to print a pointer "as if by %#x", meaning the "0x" prefix should automatically be prepended. All other implementations out there (glibc, Linux, even libpayload) do this, so we should make coreboot match. This patch changes vtxprintf() accordingly and removes any explicit instances of "0x%p" from existing format strings. How to handle zero padding is less clear: the official POSIX definition above technically says there should be no automatic zero padding, but in practice most other implementations seem to do it and I assume most programmers would prefer it. The way chosen here is to always zero-pad to 32 bits, even on a 64-bit system. The rationale for this is that even on 64-bit systems, coreboot always avoids using any memory above 4GB for itself, so in practice all pointers should fit in that range and padding everything to 64 bits would just hurt readability. Padding it this way also helps pointers that do exceed 4GB (e.g. prints from MMU config on some arm64 systems) stand out better from the others.

2019-11-14lib/fmap: Add optional pre-RAM cacheJulius Werner
This patch adds an optional pre-RAM cache for the FMAP which most platforms should be able to use, complementing the recently added post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP about half a dozen times from flash in verstage, which will all be coalesced into a single read with this patch. It will also help future vboot improvements since when FMAP reads become "free" vboot doesn't need to keep track of so much information separately. In order to make sure we have a single, well-defined point where the new cache is first initialized, eliminate the build-time hardcoding of the CBFS section offsets, so that all CBFS accesses explicitly read the FMAP. Add FMAP_CACHEs to all platforms that can afford it (other than the RISC-V things where I have no idea how they work), trying to take the space from things that look like they were oversized anyway (pre-RAM consoles and CBFS caches).

2019-11-03arch/x86: Use the stage argument to implement cbmem_topArthur Heymans
Currently all stages that need cbmem need an implementation of a cbmem_top function. On FSP and AGESA platforms this proves to be painful and a pointer to the top of lower memory if often passed via lower memory (e.g. EBDA) or via a PCI scratchpad register. The problem with writing to lower memory is that also need to be written on S3 as one cannot assume it to be still there. Writing things on S3 is always a fragile thing to do. A very generic solution is to pass cbmem_top via the program argument. It should be possible to implement this solution on every architecture. Instead trying to figure out which files can be removed from stages and which cbmem_top implementations need with preprocessor, rename all cbmem_top implementation to cbmem_top_romstage.

2019-11-03cpu/x86/tsc: Flip and rename TSC_CONSTANT_RATE to UNKNOWN_TSC_RATEKyösti Mälkki
The x86 timers are a bit of a mess. Cases where different stages use different counters and timestamps use different counters from udelays. The original intention was to only flip TSC_CONSTANT_RATE Kconfig to NOT_CONSTANT_TSC_RATE. The name would be incorrect though, those counters do run with a constant rate but we just lack tsc_freq_mhz() implementation for three platforms. Note that for boards with UNKNOWN_TSC_RATE=y, each stage will have a slow run of calibrate_tsc_with_pit(). This is easy enough to fix with followup implementation of tsc_freq_mhz() for the platforms. Implementations with LAPIC_MONOTONIC_TIMER typically will not have tsc_freq_mhz() implemented and default to UNKNOWN_TSC_RATE. However, as they don't use TSC for udelay() the slow calibrate_tsc_with_pit() is avoided. Because x86/tsc_delay.tsc was using two different guards and nb/via/vx900 claimed UDELAY_TSC, but pulled UDELAY_IO implementation, we also switch that romstage to use UDELAY_TSC.
