2017-05-05cr50: check if the new image needs to be enabled and act on itVadim Bendebury
The AP sends the Cr50 a request to enable the new firmware image. If the new Cr50 image was found and enabled, the AP expects the Cr50 to reset the device in 1 second. While waiting for the Cr50 to reset, the AP logs a newly defined event and optionally shuts down the system. By default the x86 systems power off as shutting those systems down is not board specific.

The CR50 TPM can do both SPI and I2C communication. However, there's situations where policy needs to be applied for CR50 generically regardless of the I/O transport. Therefore add MAINBOARD_HAS_TPM_CR50 to encompass that. Additionally, once the mainboard has selected CR50 TPM automatically select MAINBOARD_HAS_TPM2 since CR50 TPM is TPM 2.0.

2017-03-28vboot: Move remaining features out of vendorcode/google/chromeosJulius Werner
This patch attempts to finish the separation between CONFIG_VBOOT and CONFIG_CHROMEOS by moving the remaining options and code (including image generation code for things like FWID and GBB flags, which are intrinsic to vboot itself) from src/vendorcode/google/chromeos to src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig options, and clean up menuconfig visibility for them (i.e. some options were visible even though they were tied to the hardware while others were invisible even though it might make sense to change them).

2017-03-28vboot: Assume EC_SOFTWARE_SYNC and VIRTUAL_DEV_SWITCH by defaultJulius Werner
The virtualized developer switch was invented five years ago and has been used on every vboot system ever since. We shouldn't need to specify it again and again for every new board. This patch flips the Kconfig logic around and replaces CONFIG_VIRTUAL_DEV_SWITCH with CONFIG_PHYSICAL_DEV_SWITCH, so that only a few ancient boards need to set it and it fits better with CONFIG_PHYSICAL_REC_SWITCH. (Also set the latter for Lumpy which seems to have been omitted incorrectly, and hide it from menuconfig since it's a hardware parameter that shouldn't be configurable.) Since almost all our developer switches are virtual, it doesn't make sense for every board to pass a non-existent or non-functional developer mode switch in the coreboot tables, so let's get rid of that. It's also dangerously confusing for many boards to define a get_developer_mode() function that reads an actual pin (often from a debug header) which will not be honored by coreboot because CONFIG_PHYSICAL_DEV_SWITCH isn't set. Therefore, this patch removes all those non-functional instances of that function. In the future, either the board has a physical dev switch and must define it, or it doesn't and must not. In a similar sense (and since I'm touching so many board configs anyway), it's annoying that we have to keep selecting EC_SOFTWARE_SYNC. Instead, it should just be assumed by default whenever a Chrome EC is present in the system. This way, it can also still be overridden by menuconfig.

2017-03-09vboot/tpm2: enable nvmem commits on cr50 when writing firmware secdataAaron Durbin
cr50 by default delays nvmem commits internally from the point of reset to accumulate change state. However, the factory process can put a board into dev mode through the recovery screen. This state is stored in the TPM's nvmem space. When the factory process is complete a disable_dev_request and battery_cutoff_request is performed. This leads to disabling the dev mode in TPM, but the battery is subsequently cut off so the nvmem contents never stick. Therefore, whenever antirollback_write_space_firmware() is called we know there was a change in secdata so request cr50 to immediately enable nvmem commits going forward. This allows state changes to happen immediately. The fallout from this is that when secdata is changed that current boot will take longer because every transaction that writes to TPM nvmem space will perform a write synchronously. All subsequent boots do not have that effect. It should also be noted that this approach to the implementation is a pretty severe layering violation. However, the current TPM APIs don't lend themselves well to extending commands or re-using code outside of the current routines which inherently assume all knowledge of every command (in conflict with vendor commands since those are vendor-specific by definition).

On some x86 platforms (skylake, apollolake), we observe reboots at different steps during the FSP initialization.

2016-06-23kconfig: allow various tpm type and interface permutationsVadim Bendebury
Until now it was assumed that all TPM devices were of the same type (TCG 1.2 spec compliant) and x86 based boards had LPC connected TPMs and all other boards had I2C connected TPMs. With the advent of TPM2 specification there is a need to be able to configure different combinations of TPM types (TPM or TPM2) and interfaces (LPC, I2C and SPI). This patch allows to do it. Picking Chrome OS still assumes that the board has a TPM device, but adding MAINBOARD_HAS_TPM2 to the board's Kconfig will trigger including of TPM2 instead. MAINBOARD_HAS_LPC_TPM forces the interface to be set to LPC, adding SPI_TPM to the board config switches interface choice to SPI, and if neither of the two is defined, the interface is assumed to be I2C.

2016-06-12Kconfig: Set VBOOT_OPROM_MATTERS for relevant non-x86 devicesJulius Werner
The VBOOT_OPROM_MATTERS configuration option signals to vboot that the board can skip display initialization in the normal boot path. It's name is a left-over from a time when this could only happen by avoiding loading the VGA option ROM on x86 devices. Now we have other boards that can skip their native display initialization paths too, and the effect to vboot is the same. (Really, we should rename oprom_matters and oprom_loaded to display_skippable and display_initialized or something, but I don't think that's worth the amount of repositories this would need to touch.) The only effect this still has in today's vboot is to reboot and explicitly request display initialization for EC software sync on VBOOT_EC_SLOW_UPDATE devices (which we haven't had yet on ARM). Still, the vboot flag just declares the capability (for skipping display init), and it should be set correctly regardless of whether that actually makes a difference on a given platform (right now). This patch updates all boards/SoCs that have a conditional path based on display_init_required() accordingly.

2016-02-22cbfs: Add LZ4 in-place decompression support for pre-RAM stagesJulius Werner
This patch ports the LZ4 decompression code that debuted in libpayload last year to coreboot for use in CBFS stages (upgrading the base algorithm to LZ4's dev branch to access the new in-place decompression checks). This is especially useful for pre-RAM stages in constrained SRAM-based systems, which previously could not be compressed due to the size requirements of the LZMA scratchpad and bounce buffer. The LZ4 algorithm offers a very lean decompressor function and in-place decompression support to achieve roughly the same boot speed gains (trading compression ratio for decompression time) with nearly no memory overhead. For now we only activate it for the stages that had previously not been compressed at all on non-XIP (read: non-x86) boards. In the future we may also consider replacing LZMA completely for certain boards, since which algorithm wins out on boot speed depends on board-specific parameters (architecture, processor speed, SPI transfer rate, etc.). BRANCH=None BUG=None TEST=Built and booted Oak, Jerry, Nyan and Falco. Measured boot time on Oak to be about ~20ms faster (cutting load times for affected stages almost in half).

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).

The Chrome OS verified boot path supported multiple CBFS instances in the boot media as well as stand-alone assets sitting in each vboot RW slot. Remove the support for the stand-alone assets and always use CBFS accesses as the way to retrieve data. This is implemented by adding a cbfs_locator object which is queried for locating the current CBFS. Additionally, it is also signalled prior to when a program is about to be loaded by coreboot for the subsequent stage/payload. This provides the same opportunity as previous for vboot to hook in and perform its logic. BUG=chromium:445938 BRANCH=None TEST=Built and ran on glados.

2015-10-28vboot: check vb2_shared_data flags for manual recoveryDaisuke Nojiri
vboot handoff should look at flags in struct vb2_shared_data when translating flags to VBSD_BOOT_REC_SWITCH_ON because VBSD_BOOT_REC_SWITCH_ON is supposed to indicate whether manual recovery was triggered or not while vb2_sd->recovery_reason will be able to provide that information only in some cases after CL:307586 is checked in. For example, this fixes a recovery loop problem: Without this fix, vb2_sd->recovery_reason won't be set to VB2_RECOVERY_RO_MANUAL when user hits esc+refresh+power at 'broken' screen. In the next boot, recovery_reason will be set to whatever reason which caused 'broken' screen. So, if we check recovery_reason == VB2_RECOVERY_RO_MANUAL, we won't set vb_sd->flags to VBSD_BOOT_REC_SWITCH_ON. That'll cause a recovery loop because VbBootRecovery traps us again in the 'broken' screen after not seeing VBSD_BOOT_REC_SWITCH_ON.

2015-10-14x86: add standalone verstage supportAaron Durbin
To support x86 verstage one needs a working buffer for vboot. That buffer resides in the cache-as-ram region which persists across verstage and romstage. The current assumption is that verstage brings cache-as-ram up and romstage tears cache-as-ram down. The timestamp, cbmem console, and the vboot work buffer are persistent through in both romstage and verstage. The vboot work buffer as well as the cbmem console are permanently destroyed once cache-as-ram is torn down. The timestamp region is migrated. When verstage is enabled the assumption is that _start is the romstage entry point. It's currently expected that the chipset provides the entry point to romstage when verstage is employed. Also, the car_var_*() APIs use direct access when in verstage since its expected verstage does not tear down cache-as-ram. Lastly, supporting files were added to verstage-y such that an x86 verstage will build and link. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados using separate verstage.

2015-10-11vboot: prepare for x86 verstageAaron Durbin
In order to support x86 verstage proper the work buffer needs to live in cache-as-ram. However, after cache-as-ram is torn down one still needs the verification results to know which slot was selected. Though the platforms with a dedicated SRAM can just use the work buffer in SRAM, the x86 cache-as-ram platforms need a place to stash the results. For that situation cbmem is employed. This works because when cbmem is initialized cache-as-ram is still enabled. The VBOOT_DYNAMIC_WORK_BUFFER case assumes verified boot doesn't start until after cbmem is up. That doesn't change, but it's a goal to get rid of that option entirely once all other x86 platforms are moved over to pre-romstage vboot.
