2023-09-18security/vboot: Update vboot context with slot B absenceMichał Żygowski
coreboot offers two vboot schemes VBOOT_SLOTS_RW_A and VBOOT_SLOTS_RW_AB. When VBOOT_SLOTS_RW_AB is not selected then the resulting image is rather not expected to have the FW_MAIN_B FMAP region. When only RW_A region is used, vboot does additional full_reset cycles to try RW_B, even though it does not exist / the build was not configured for two RW partitions. To avoid it, a new vboot context flag has been introduced, VB2_CONTEXT_SLOT_A_ONLY, which can be set right after context initialization to inform vboot about absence of slot B. This will result in less full_reset cycles when vboot runs out of available slots and cause vboot to switch to recovery mode faster.

2023-09-14x86: Add .data section support for pre-memory stagesJeremy Compostella
x86 pre-memory stages do not support the `.data` section and as a result developers are required to include runtime initialization code instead of relying on C global variable definition. To illustrate the impact of this lack of `.data` section support, here are two limitations I personally ran into: 1. The inclusion of libgfxinit in romstage for Raptor Lake has required some changes in libgfxinit to ensure data is initialized at runtime. In addition, we had to manually map some `.data` symbols in the `_bss` region. 2. CBFS cache is currently not supported in pre-memory stages and enabling it would require to add an initialization function and find a generic spot to call it. Other platforms do not have that limitation. Hence, resolving it would help to align code and reduce compilation based restriction (cf. the use of `ENV_HAS_DATA_SECTION` compilation flag in various places of coreboot code). We identified three cases to consider: 1. eXecute-In-Place pre-memory stages - code is in SPINOR - data is also stored in SPINOR but must be linked in Cache-As-RAM and copied there at runtime 2. `bootblock` stage is a bit different as it uses Cache-As-Ram but the memory mapping and its entry code different 3. pre-memory stages loaded in and executed from Cache-As-RAM (cf. `CONFIG_NO_XIP_EARLY_STAGES`). eXecute-In-Place pre-memory stages (#1) require the creation of a new ELF segment as the code segment Virtual Memory Address and Load Memory Address are identical but the data needs to be linked in cache-As-RAM (VMA) but to be stored right after the code (LMA). Here is the output `readelf --segments` on a `romstage.debug` ELF binary. Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align LOAD 0x000080 0x02000000 0x02000000 0x21960 0x21960 R E 0x20 LOAD 0x0219e0 0xfefb1640 0x02021960 0x00018 0x00018 RW 0x4 Section to Segment mapping: Segment Sections... 00 .text 01 .data Segment 0 `VirtAddr` and `PhysAddr` are at the same address while they are totally different for the Segment 1 holding the `.data` section. Since we need the data section `VirtAddr` to be in the Cache-As-Ram and its `PhysAddr` right after the `.text` section, the use of a new segment is mandatory. `bootblock` (#2) also uses this new segment to store the data right after the code and load it to Cache-As-RAM at runtime. However, the code involved is different. Not eXecute-In-Place pre-memory stages (#3) do not really need any special work other than enabling a data section as the code and data VMA / LMA translation vector is the same. TEST=#1 and #2 verified on rex and qemu 32 and 64 bits: - The `bootblock.debug`, `romstage.debug` and `verstage.debug` all have data stored at the end of the `.text` section and code to copy the data content to the Cache-As-RAM. - The CBFS stages included in the final image has not improperly relocated any of the `.data` section symbol. - Test purposes global data symbols we added in bootblock, romstage and verstage are properly accessible at runtime #3: for "Intel Apollolake DDR3 RVP1" board, we verified that the generated romstage ELF includes a .data section similarly to a regular memory enabled stage.

2023-01-10chromeos/cr50_enable_update.c: Clear EC AP_IDLE flagDerek Huang
When AP boots up after Cr50 firmware update and reboot, AP finds that Cr50 reset is required for Cr50 to pick the new firmware so it trigger Cr50 reset and power off the system, AP expects system will power on automatically after Cr50 reset. However this is not the case for Chromebox, Chromebox EC set AP_IDLE flag when system is shutting down, when AP_IDLE flag is set in EC, the system stays at S5/G3 and wait for power button presssend. It cause an issue in factory that the operator needs to press power button to power on the DUT after Cr50 firmware update. This patch sends EC command to direct EC to clear AP_IDLE flag after AP shutdown so AP can boot up when Cr50 reset.

2022-08-22Add SBOM (Software Bill of Materials) GenerationMaximilian Brune
Firmware is typically delivered as one large binary image that gets flashed. Since this final image consists of binaries and data from a vast number of different people and companies, it's hard to determine what all the small parts included in it are. The goal of the software bill of materials (SBOM) is to take a firmware image and make it easy to find out what it consists of and where those pieces came from. Basically, this answers the question, who supplied the code that's running on my system right now? For example, buyers of a system can use an SBOM to perform an automated vulnerability check or license analysis, both of which can be used to evaluate risk in a product. Furthermore, one can quickly check to see if the firmware is subject to a new vulnerability included in one of the software parts (with the specified version) of the firmware.

2022-04-21tpm: Refactor TPM Kconfig dimensionsJes B. Klinke
Break TPM related Kconfig into the following dimensions: TPM transport support: config CRB_TPM config I2C_TPM config SPI_TPM config MEMORY_MAPPED_TPM (new) TPM brand, not defining any of these is valid, and result in "generic" support: config TPM_ATMEL (new) config TPM_GOOGLE (new) config TPM_GOOGLE_CR50 (new, implies TPM_GOOGLE) config TPM_GOOGLE_TI50 (new to be used later, implies TPM_GOOGLE) What protocol the TPM chip supports: config MAINBOARD_HAS_TPM1 config MAINBOARD_HAS_TPM2 What the user chooses to compile (restricted by the above): config NO_TPM config TPM1 config TPM2 The following Kconfigs will be replaced as indicated: config TPM_CR50 -> TPM_GOOGLE config MAINBOARD_HAS_CRB_TPM -> CRB_TPM config MAINBOARD_HAS_I2C_TPM_ATMEL -> I2C_TPM && TPM_ATMEL config MAINBOARD_HAS_I2C_TPM_CR50 -> I2C_TPM && TPM_GOOGLE config MAINBOARD_HAS_I2C_TPM_GENERIC -> I2C_TPM && !TPM_GOOGLE && !TPM_ATMEL config MAINBOARD_HAS_LPC_TPM -> MEMORY_MAPPED_TPM config MAINBOARD_HAS_SPI_TPM -> SPI_TPM && !TPM_GOOGLE && !TPM_ATMEL config MAINBOARD_HAS_SPI_TPM_CR50 -> SPI_TPM && TPM_GOOGLE Signed-off-by: Jes B.
