2017-09-14timestamp: Add function to get time since bootWerner Zeh
Add a function to retrieve the elapsed time since boot. For that purpose use the base time in the timestamp table among with the current timestamp at call time of the function. So more precise the returned time is the elapsed time since the timestamp was initialized scaled in microseconds. This was chosen to get a reliable value even on platforms where the TSC might not be reset on software reset or warm start.

2017-06-21cr50: process uninitialized values gracefullyVadim Bendebury
The vboot code tries reading rollback protection indices from the TPM, and if the attempt to read returns TPM_E_BADINDEX, it decides that the TPM has not yet been initialized for the Chromebook use, and needs to be taken through the factory initialization sequence. TPM_E_BADINDEX is an internal representation of the TPM error 0x28b, generated on attempts to read a non existing NVMEM space. If the space exists, but has never been written the TPM returns error 0x14a. This condition (the space exists but not written) could happen if the previous factory initialization attempt was interrupted right after the space was created. Let's map this error to the same internal representation (TPM_E_BADINDEX) so that the Chrome OS device could recover when this condition occurs. BRANCH=reef, gru BUG=b:37443842 TEST=verified that the Pyro device stuck in TPM error state recovered when this patch was applied.

2017-06-13Consolidate reset API, add generic reset_prepare mechanismJulius Werner
There are many good reasons why we may want to run some sort of generic callback before we're executing a reset. Unfortunateley, that is really hard right now: code that wants to reset simply calls the hard_reset() function (or one of its ill-differentiated cousins) which is directly implemented by a myriad of different mainboards, northbridges, SoCs, etc. More recent x86 SoCs have tried to solve the problem in their own little corner of soc/intel/common, but it's really something that would benefit all of coreboot. This patch expands the concept onto all boards: hard_reset() and friends get implemented in a generic location where they can run hooks before calling the platform-specific implementation that is now called do_hard_reset(). The existing Intel reset_prepare() gets generalized as soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now easily be added later if necessary). We will also use this central point to ensure all platforms flush their cache before reset, which is generally useful for all cases where we're trying to persist information in RAM across reboots (like the new persistent CBMEM console does). Also remove cpu_reset() completely since it's not used anywhere and doesn't seem very useful compared to the others.

2017-05-18cbmem_console: Improve 'cbmem -1' behavior for truncated pre-CBMEM logsJulius Werner
The 'cbmem -1' flag that cuts off console output before the last boot will ignore content from earlier stages if it was truncated due to lack of pre-CBMEM console space. This patch makes the "log truncated" message more specific and adds it as an additional cut-off marker to 'cbmem -1' to counteract that problem. Also raise the log level of the coreboot banner one step to BIOS_NOTICE to make it more likely to be included in the output for 'cbmem -1' to find. (I believe NOTICE is reasonable but I wouldn't want to go as far as WARN which should be reserved for actual problems. Of course this is not ideal, but then again, our whole log-level system really isn't... it would be better if we could make it always print a banner to the CBMEM console without affecting the UART at the same time, but that would require a larger amount of work.)

2017-04-20Turn CBMEM console into a ring buffer that can persist across rebootsJulius Werner
This patch allows the CBMEM console to persist across reboots, which should greatly help post factum debugging of issues involving multiple reboots. In order to prevent the console from filling up, it will instead operate as a ring buffer that continues to evict the oldest lines once full. (This means that if even a single boot doesn't fit into the buffer, we will now drop the oldest lines whereas previous code would've dropped the newest lines instead.) The console control structure is modified in a sorta backwards-compatible way, so that new readers can continue to work with old console buffers and vice versa. When an old reader reads a new buffer that has already once overflowed (i.e. is operating in true ring buffer mode) it will print lines out of order, but it will at least still print out the whole console content and not do any illegal memory accesses (assuming it correctly implemented cursor overflow as it was already possible before this patch). BUG=chromium:651966 TEST=Rebooted and confirmed output repeatedly on a Kevin and a Falco. Also confirmed correct behavior across suspend/resume for the latter.

There's a missing closing brace in fillbits function of jpeg.c which caused an avalanche of compilation errors. This was introduced in commit 491c5b60 (src/lib: Move assignment out of if condition) which was reviewed in gerrit at https://review.coreboot.org/18761 and it prevents coreboot from building when CONFIG_BOOTSPLASH is set.

2017-03-28Remove libverstage as separate library and source file classJulius Werner
In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are linked directly into the bootblock or the romstage. However, they're still compiled with a separate "libverstage" source file class, linked into an intermediate library and then linked into the final destination stage. There is no obvious benefit to doing it this way and it's unclear why it was chosen in the first place... there are, however, obvious disadvantages: it can result in code that is used by both libverstage and the host stage to occur twice in the output binary. It also means that libverstage files have their separate compiler flags that are not necessarily aligned with the host stage, which can lead to weird effects like <rules.h> macros not being set the way you would expect. In fact, VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86 because their libverstage code that gets compiled into the romstage sets ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to run pre-migration. This patch resolves these problems by removing the separate library. There is no more difference between the 'verstage' and 'libverstage' classes, and the source files added to them are just treated the same way a bootblock or romstage source files in configurations where the verstage is linked into either of these respective stages (allowing for the normal object code deduplication and causing those files to be compiled with the same flags as the host stage's files). Tested this whole series by booting a Kevin, an Elm (both with and without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

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).

2017-03-23cr50: add unmarshaling of vendor commands and process 'enable_update'Vadim Bendebury
The upcoming Cr50 firmware changes will require the AP to enable the previously downloaded Cr50 firmware update(s). A new vendor command (TPM2_CR50_SUB_CMD_TURN_UPDATE_ON) is used for that. The command accepts one parameter - a timeout value in range of 0 to 1000 ms. When processing the command the Cr50 checks if the alternative RO or RW image(s) need to be enabled, and if so - enables them and returns to the host the number of enabled headers. If the vendor command requested a non-zero timeout, the Cr50 starts a timer to trigger system reboot after the requested timeout expires. The host acts on the number of enabled headers - if the number is nonzero, the host prepares the device to be reset and waits for the Cr50 to reboot the device after timeout expires. This patch also adds more formal vendor command marshaling/unmarshaling to make future additions easier. BRANCH=gru,reef BUG=b:35580805 TEST=with the actual user of this code in the next patch verified that the cr50 update is enabled as expected.
