2021-01-22vendorcode/google/chromeos: Build CSE Board Reset in RomstageKarthikeyan Ramasubramanian
CSE Firmware Sync is being performed in romstage currently. But the CSE board reset is not included as part of romstage. This causes the CSE firmware sync to use global reset instead of EC assisted AP reset with the old Cr50 Firmware version. Include the board specific CSE reset in romstage. BUG=b:171731175,b:177795247 BRANCH=dedede,volteer,puff TEST=Ensured that the Drawlat boots to OS with both old(0.0.22) and new(0.6.7) Cr50 FW versions.

2019-10-24google/chromeos: Add a library to get DSM calibration dataCheng-Yi Chiang
On ChromeOS, there will be VPD values for dynamic speaker management (DSM) calibration data. They are resistor calibration values and temperature during calibration.

Known keys are: "dsm_calib_r0_0" "dsm_calib_r0_1" "dsm_calib_r0_2" "dsm_calib_r0_3" "dsm_calib_temp_0" For now these values are unsigned decimal numbers greater than 0. This library will be used for RT1011 device driver in the patch series. Note that in the future we may encode more values into this VPD field if needed. We retain the flexibility for coreboot device driver or codec driver to decode/parse the VPD values based on the needed use case per-board.

2016-02-09chromeos: Add vbnv wrapper for the different backendsDuncan Laurie
Add a wrapper around the vbnv implementations and call into the different backend functions from there. Also move some of the common functions to the common code and simplify the backend drivers. This will allow some of the code to be re-used so the CMOS backend can backup the data into the flash backend. One side effect of this is that the cache of VBNV was removed from CMOS and EC backends and moved into the VBNV wrapper, but the flash backend also still has a separate cache because it has more state and complexity in the implementation. The wrapper cached data is not used for normal vbnv_read/vbnv_write because some callers need the ability to force a write if the backend storage is cleared (i.e. CMOS clear).

2015-04-17chromeos: Provide common watchdog reboot supportJulius Werner
Many ChromeOS devices use a GPIO to reset the system, in order to guarantee that the TPM cannot be reset without also resetting the CPU. Often chipset/SoC hardware watchdogs trigger some kind of built-in CPU reset, bypassing this GPIO and thus leaving the TPM locked. These ChromeOS devices need to detect that condition in their bootblock and trigger a second (proper) reboot. This patch adds some code to generalize this previously mainboard-specific functionality and uses it on Veyron boards. It also provides some code to add the proper eventlog entry for a watchdog reset. Since the second reboot has to happen before firmware verification and the eventlog is usually only initialized afterwards, we provide the functionality to place a tombstone in a memlayout-defined location (which could be SRAM or some MMIO register that is preserved across reboots).

2015-04-10chromeos: Add a function to copy VPD WiFi calibration data to CBMEMVadim Bendebury
This patch adds functions looking in the VPD for WiFi calibration data, and if found, copying the calibration blobs into CBMEM. Two possible key names templates are used: wifi_base64_calibrationX and wifi_calibrationX, where X is replaced by the WiFi interface number. Up to four interfaces can be provisioned. The calibration data will be retrieved from CBMEM by the bootloader and placed into the device tree before starting the kernel. The structure of the WiFi calibration data CBMEM entry is defined locally: it is a concatenation of the blob names and their contents. Each blob is padded as necessary to make sure that the size divisible by four. To make sure that the exactly required amount of memory is allocated for the CBMEM entry, the function first scans the VPD, caching the information about the available blobs and calculating their combined size. Then the required size CBMEM entry is allocates and the blobs are copied into it. BRANCH=storm BUG=chrome-os-partner:32611 TEST=when this function is called, and the VPD includes calibration data blobs, the WIFI entry shows up in the list of CBMEM entries reported by coreboot.

2015-04-06New mechanism to define SRAM/memory map with automatic bounds checkingJulius Werner
This patch creates a new mechanism to define the static memory layout (primarily in SRAM) for a given board, superseding the brittle mass of Kconfigs that we were using before. The core part is a memlayout.ld file in the mainboard directory (although boards are expected to just include the SoC default in most cases), which is the primary linker script for all stages (though not rmodules for now). It uses preprocessor macros from <memlayout.h> to form a different valid linker script for all stages while looking like a declarative, boilerplate-free map of memory addresses to the programmer. Linker asserts will automatically guarantee that the defined regions cannot overlap. Stages are defined with a maximum size that will be enforced by the linker. The file serves to both define and document the memory layout, so that the documentation cannot go missing or out of date. The mechanism is implemented for all boards in the ARM, ARM64 and MIPS architectures, and should be extended onto all systems using SRAM in the future. The CAR/XIP environment on x86 has very different requirements and the layout is generally not as static, so it will stay like it is and be unaffected by this patch (save for aligning some symbol names for consistency and sharing the new common ramstage linker script include). BUG=None TEST=Booted normally and in recovery mode, checked suspend/resume and the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies with ToT and looked for red flags.

2015-01-13vboot2: add verstageDaisuke Nojiri
Verstage will host vboot2 for firmware verification. It's a stage in the sense that it has its own set of toolchains, compiler flags, and includes. This allows us to easily add object files as needed. But it's directly linked to bootblock. This allows us to avoid code duplication for stage loading and jumping (e.g. cbfs driver) for the boards where bootblock has to run in a different architecture (e.g. Tegra124). To avoid name space conflict, verstage symbols are prefixed with verstage_. TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.

2014-05-06Introduce stage-specific architecture for corebootFurquan Shaikh
Make all three coreboot stages (bootblock, romstage and ramstage) aware of the architecture specific to that stage i.e. we will have CONFIG_ARCH variables for each of the three stages. This allows us to have an SOC with any combination of architectures and thus every stage can be made to run on a completely different architecture independent of others. Thus, bootblock can have an x86 arch whereas romstage and ramstage can have arm32 and arm64 arch respectively. These stage specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain and compiler flags for every stage. These options can be considered as either arch or modes eg: x86 running in different modes or ARM having different arch types (v4, v7, v8). We have got rid of the original CONFIG_ARCH option completely as every stage can have any architecture of its own. Thus, almost all the components of coreboot are identified as being part of one of the three stages (bootblock, romstage or ramstage). The components which cannot be classified as such e.g. smm, rmodules can have their own compiler toolset which is for now set to *_i386. Hence, all special classes are treated in a similar way and the compiler toolset is defined using create_class_compiler defined in Makefile. In order to meet these requirements, changes have been made to CC, LD, OBJCOPY and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others. Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the toolsets are defined using create_class_compiler. Few additional macros have been introduced to identify the class to be used at various points, e.g.: CC_$(class) derives the $(class) part from the name of the stage being compiled. We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER as they do not make any sense for coreboot as a whole. All these attributes are associated with each of the stages.

2013-03-22romstage: add support for vboot firmware selectionAaron Durbin
This patch implements support for vboot firmware selection. The vboot support is comprised of the following pieces: 1. vboot_loader.c - this file contains the entry point, vboot_verify_firmware(), for romstage to call in order to perform vboot selection. The loader sets up all the data for the wrapper to use. 2. vboot_wrapper.c - this file contains the implementation calling the vboot API. It calls VbInit() and VbSelectFirmware() with the data supplied by the loader. The vboot wrapper is compiled and linked as an rmodule and placed in cbfs as 'fallback/vboot'. It's loaded into memory and relocated just like the way ramstage would be. After being loaded the loader calls into wrapper. When the wrapper sees that a given piece of firmware has been selected it parses firmware component information for a predetermined number of components. Vboot result information is passed to downstream users by way of the vboot_handoff structure. This structure lives in cbmem and contains the shared data, selected firmware, VbInitParams, and parsed firwmare components. During ramstage there are only 2 changes: 1. Copy the shared vboot data from vboot_handoff to the chromeos acpi table. 2. If a firmware selection was made in romstage the boot loader component is used for the payload. Noteable Information: - no vboot path for S3. - assumes that all RW firmware contains a book keeping header for the components that comprise the signed firmware area. - As sanity check there is a limit to the number of firmware components contained in a signed firmware area. That's so that an errant value doesn't cause the size calculation to erroneously read memory it shouldn't. - RO normal path isn't supported. It's assumed that firmware will always load the verified RW on all boots but recovery. - If vboot requests memory to be cleared it is assumed that the boot loader will take care of that by looking at the out flags in VbInitParams. Built and booted. Noted firmware select worked on an image with RW firmware support. Also checked that recovery mode worked as well by choosing the RO path.
