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>
2020-11-22drivers/tpm: Move PPI stubPatrick Rudolph
As preparation to a full PPI implementation move the acpi code out of the pc80/tpm/tis driver into the generic tpm driver folder. This doesn't change any functionality.

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.
