drivers/tpm/Kconfig: Rename TPM_INIT to TPM_INIT_RAMSTAGE 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.

drivers/tpm: Move PPI stub 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.

drivers/tpm: Implement full PPI 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> 2020-09-21 09:49:31 +02:00			`ifeq ($(CONFIG_TPM_PPI),y)`
