2024-04-15drivers/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.

2024-03-28security/tpm: replace CONFIG(TPMx) checks with runtime checkSergii 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.

2022-10-05drivers/crb: Initialize Intel PTT control areaMichał 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.

2019-12-04Change all clrsetbits_leXX() to clrsetbitsXX()Julius Werner
This patch changes all existing instances of clrsetbits_leXX() to the new endian-independent clrsetbitsXX(), after double-checking that they're all in SoC-specific code operating on CPU registers and not actually trying to make an endian conversion. This patch was created by running sed -i -e 's/\([cs][le][rt]bits\)_le\([136][624]\)/\1\2/g' across the codebase and cleaning up formatting a bit.
