2024-04-16	security/tpm: support compiling in multiple TPM drivers	Sergii Dmytruk
	Starting from here CONFIG_TPM1 and CONFIG_TPM2 are no longer mutually exclusive. Change-Id: I44c5a1d825afe414c2f5c2c90f4cfe41ba9bef5f Ticket: https://ticket.coreboot.org/issues/433 Signed-off-by: Sergii Dmytruk <sergii.dmytruk@3mdeb.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/69162 Reviewed-by: Julius Werner <jwerner@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2024-04-15	drivers/crb: use crb_tpm_ prefix instead of tpm2_	Sergii Dmytruk
	This prevents name clashes with drivers/spi/tpm and allows both to be potentially compiled in at the same time.

2024-03-28	security/tpm: replace CONFIG(TPMx) checks with runtime check	Sergii Dmytruk
	This prepares the code for enabling both CONFIG_TPM1 and CONFIG_TPM2 during compilation, in which case actual TPM family in use can be determined at runtime. In some places both compile-time and runtime checks are necessary. Yet in places like probe functions runtime state checks don't make sense as runtime state is defined by results of probing.

	Convert TPM functions to return TPM error codes(referred to as tpm_result_t) values to match the TCG standard.

2022-10-05	drivers/crb: Initialize Intel PTT control area	Michał Żygowski
	On newer systems such as Alder Lake it has been noticed that Intel PTT control area is not writable until PTT is switched to ready state. The EDK2 CRB drivers always initialize the command/response buffer address and size registers before invoking the TPM command. See STEP 2 in PtpCrbTpmCommand function in tianocore/edk2/SecurityPkg/Library/Tpm2DeviceLibDTpm/Tpm2Ptp.c Doing the same in coreboot allowed to perform PTT TPM startup successfully and measure the components to PCRs in ramstage on an Alder Lake S platform. TEST=Enable measured boot and see Intel PTT is started successfully and no errors occur during PCR extends on MSI PRO Z690-A DDR4 WIFI.

	Add the Command Response Buffer which is defined in the TPM 2.0 Specs. CRB can be specified with MAINBOARD_HAS_CRB_TPM, even though it is actually SoC/SB specific.
