2021-05-06security/tpm: Add option to init TPM in bootblockArthur Heymans
When using a hardware assisted root of trust measurement, like Intel TXT/CBnT, the TPM init needs to happen inside the bootblock to form a proper chain of trust.

2021-04-09drivers/tpm/Kconfig: Rename TPM_INIT to TPM_INIT_RAMSTAGEArthur Heymans
Rename the Kconfig parameter to more accurately reflect what it does. TPM can be initialised in a different stage too, for instance with VBOOT it is done in verstage.

2021-04-06drivers/tpm/Kconfig: TPM_INIT for measured boot onlyFrans Hendriks
TPM_INIT depends on VBOOT but should also depend on VENDORCODE_ELTAN_xBOOT. Add dependency. TPM_INIT will be enable for measured boot only. BUG = NA TEST = Boot Facebook FB1701 with possible combinaties of VBOOT, measured boot and eltan security.

2020-12-21drivers/tpm: Implement full PPIPatrick Rudolph
Implement the ACPI PPI interface as described in "TCG PC Client Physical Presence Interface Specification" Version 1.3. Add a new Kconfig that allows to use the full PPI instead of the stub version compiled in. This doesn't add code to execute the PPI request, as that's up to the payload with graphical UI support. Tested on GNU/Linux 5.6 using the sysfs interface at: /sys/class/tpm/tpm0/ppi/ Change-Id: Ifffe1d9b715e2c37568e1b009e86c298025c89ac Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/45568 Reviewed-by: Angel Pons <th3fanbus@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2018-07-25drivers/tpm: Add TPM ramstage driver for devices without vboot.Philipp Deppenwiese
Logic: If vboot is not used and the tpm is not initialized in the romstage makes use of the ramstage driver to initialize the TPM globally without having setup calls in lower SoC level implementations. * Add TPM driver in ramstage chip init which calls the tpm_setup function. * Purge all occurrences of TPM init code and headers. * Only compile TIS drivers into ramstage except for vboot usage. * Remove Google Urara/Rotor TPM support because of missing i2c driver in ramstage.
