2022-09-02	cbfs/vboot: Adapt to new vb2_digest API	Julius Werner
	CL:3825558 changes all vb2_digest and vb2_hash functions to take a new hwcrypto_allowed argument, to potentially let them try to call the vb2ex_hwcrypto API for hash calculation. This change will open hardware crypto acceleration up to all hash calculations in coreboot (most notably CBFS verification). As part of this change, the vb2_digest_buffer() function has been removed, so replace existing instances in coreboot with the newer vb2_hash_calculate() API. Due to the circular dependency of these changes with vboot, this patch also needs to update the vboot submodule: Updating from commit id 18cb85b5: 2load_kernel.c: Expose load kernel as vb2_api to commit id b827ddb9: tests: Ensure auxfw sync runs after EC sync This brings in 15 new commits.

2021-03-30	security: vboot: Clarify PCR extension algorithms/sizes	Julius Werner
	The PCR algorithms used for vboot are frequently causing confusion (e.g. see CB:35645) because depending on the circumstances sometimes a (zero-extended) SHA1 value is interpreted as a SHA256, and sometimes a SHA256 is interpreted as a SHA1. We can't really "fix" anything here because the resulting digests are hardcoded in many generations of Chromebooks, but we can document and isolate it better to reduce confusion. This patch adds an explanatory comment and fixes both algorithms and size passed into the lower-level TPM APIs to their actual values (whereas it previously still relied on the TPM 1.2 TSS not checking the algorithm type, and the TPM 2.0 TSS only using the size value for the TCPA log and not the actual TPM operation).

2019-09-21	vboot: extend BOOT_MODE_PCR to SHA256 bank on TPM2	Andrey Pronin
	With the support of various algorithms and banks in tlcl_extend(), digest_algo parameter of tpm_extend_pcr() started defining the target PCR bank in TPM2 case. The OS expects coreboot to extend the SHA256 bank of BOOT_MODE_PCR. The value that the OS expects coreboot to extend into BOOT_MODE_PCR is the SHA1 digest of mode bits extended to the length of SHA256 digest by appending zero bytes. Thus the correct value for digest_algo passed into tpm_extend_pcr() for BOOT_MODE_PCR is TPM_ALG_SHA256. This didn't matter until adding the support for multiple digest introduced by patches like https://review.coreboot.org/c/coreboot/+/33252, as tlcl_extend always used SHA256 bank before.

2019-08-06	security/vboot: Add Support for Intel PTT	Christian Walter
	Add support for Intel PTT. For supporting Intel PTT we need to disable read and write access to the TPM NVRAM during the bootblock. TPM NVRAM will only be available once the DRAM is initialized. To circumvent this, we mock secdata if HAVE_INTEL_PTT is set. The underlying problem is, that the iTPM only supports a stripped down instruction set while the Intel ME is not fully booted up. Details can be found in Intel document number 571993 - Paragraph 2.10.
