2018-02-21driver/uart: Introduce a way for mainboard to override the baudrateJulien Viard de Galbert
The rationale is to allow the mainboard to override the default baudrate for instance by sampling GPIOs at boot. A new configuration option is available for mainboards to select this behaviour. It will then have to define the function get_uart_baudrate to return the computed baudrate.

2018-02-15drivers/i2c: Add chip driver for I/O expander PCA9538Werner Zeh
The chip PCA9538 is a 8 bit I/O expander connected to the systems I2C bus. Add a chip driver to support this chip. Beside the pure chip driver two interface functions are provided to read the state of the pins and write output values to the pins. As the slave address of this chip is hardware configurable the function pca9538_get_dev() is used to get the right slave address. This function needs to be implemented in mainboard code if one needs to use the interface functions to read and write I/O state.

Right now dw_i2c_get_soc_cfg() is expecting the SoC to implement that callback for obtaining the bus config. However, we're currently forcing another parameter of struct device so one can do the lookup. This works for Intel-based systems since the struct device was needed to program the BAR, etc. However, from an API standpoint, it just complicates matters by needing to obtain the struct device. The SoC already has knowlege of its own devices so it can get the config itself by bus number. Therefore, remove that contraint from the API.

2018-01-11intel/fsp2_0: Set boot mode default as per s3wake statusAamir Bohra
Currently bootmode default is set to FSP_BOOT_WITH_FULL_CONFIGURATION and bootmode UPD is updated in fsp_fill_mrc_cache based on mrc cache data validity. With current implementation in S3 resume path, if mrc cache data is invalid, the bootmode is not updated further and remains set at FSP_BOOT_WITH_FULL_CONFIGURATION. This results in fsp-m to get incorrect boot mode context and reinitialize memory in S3 resume path. In correct flow fspm should have correct bootmode context i.e. S3 resume and return error in case mrc cache data is invalid or not found.

2018-01-11intel/fsp2_0: Issue hard reset in S3 resume for invalid mrc cache dataAamir Bohra
In S3 resume, for cases if valid mrc cache data is not found or RECOVERY_MRC_CACHE hash verification fails, the S3 data pointer would be null and bootmode is set to BOOT_WITH_FULL_CONFIGURATION. This gets memory to be retrained in S3 flow. Data context including that of imdr root pointer would be lost, invoking a hard reset in romstage post memory init.

2017-11-22drivers/i2c/tpm/cr50: Simplify and increase init delay to 30 secondsDuncan Laurie
The Cr50 i2c driver provides separate entry points for probing and initialization, but probing function does not really do much. It also claims and releases locality on every coreboot stage, but there is no need for this - locality should be definitely claimed after reset and then it could be retained through the boot process. On top of that the driver does not properly account for long time it could take the Cr50 chip to come around to reset processing if TPM reset request was posted during a lengthy TPM operation. This patch addresses the issues as follows: - tpm_vendor_probe() and tpm_vendor_cleanup() become noops, kept around to conform to the expected driver API. - tpm_vendor_init() invokes a function to process TPM reset only in the first stage using TPM (typically verstage), the function checks if locality is claimed and if so - waits for it to be released, which indicates that TPM reset processing is over. - before claiming locality check if it is already taken, and if so - just proceed.

2017-11-21spi/tpm: claim locality just once during bootVadim Bendebury
All coreboot stages using TPM start with the same sequence: check if locality is claimed, if so, release it by writing 'active locality' bit, then try claiming it. This is actually not a proper procedure: section "5.5.2.3.1 Command Aborts" of "TCG PC Client Platform TPM Profile (PTP) Specification Level 00 Revision 00.430 Family 2" lists overwriting active locality status bit as a means of triggering TPM command abort. On top of that, none of the coreboot stages releases locality, it is enough to claim it once when device starts booting. In fact, locality being active when the device is in verstage is most likely due to delayed TPM reset processing by the Cr50 TPM: reset is an asynchronous event, and is processed once current command processing completes. The proper procedure is to wait if locality is active until it is released (which will happen when Cr50 processes reset) and then proceed to claim it. This needs to happen only during verstage, other stages using TPM are guaranteed has been claimed earlier. BRANCH=gru BUG=b:65867313 TEST=the new autotest triggering EC reset during key generation process does not cause boot failures on Fizz device any more. Below are times verstage had to wait: TPM ready after 3132 ms TPM ready after 22120 ms TPM ready after 4936 ms TPM ready after 6445 ms TPM ready after 11798 ms TPM ready after 27421 ms TPM ready after 4582 ms TPM ready after 7532 ms TPM ready after 27920 ms TPM ready after 3539 ms TPM ready after 12557 ms TPM ready after 6773 ms TPM ready after 1631 ms TPM ready after 197 ms TPM ready after 24330 ms TPM ready after 3241 ms Change-Id: Iaee04f009bcde03712483e5e03de4a3441ea32b1 Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: https://review.coreboot.org/22489 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Philipp Deppenwiese <zaolin.daisuki@gmail.com> Reviewed-by: Julius Werner <jwerner@chromium.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
