2016-07-12vboot2: tpm2 factory initialization.Vadim Bendebury
This patch adds a TPM2 specific path in the vboot2 initialization sequence when the device is turned on in the factory for the first time, namely two secure NVRAM spaces are created, with different access privileges. The higher privilege space can be modified only be the RO firmware, and the lower privilege space can be modified by both RO and RW firmware. The API is being modified to hide the TPM implementation details from the caller. Some functions previously exported as global are in fact not used anywhere else, they are being defined static. BRANCH=none BUG=chrome-os-partner:50645 TEST=when this code is enabled the two secure spaces are successfully created during factory initialization.

The actual functions have been redefined as static recently and their declarations were removed from src/include/antirollback.h, which now causes compilation problems when CONFIG_VBOOT2_MOCK_SECDATA is defined. Dropping the functions from secdata_mock.c solves the problem. BRANCH=none BUG=none TEST=compilation in mock secdata mode does not fail any more.

2015-04-20chromeos: vboot2: Add TPM PCR extension supportJulius Werner
ChromeOS/vboot devices expect the TPM PCRs 0 and 1 to be extended with digests that attest the chosen boot mode (developer/recovery) and the HWID in a secure way. This patch uses the newly added vboot2 support functions to fetch these digests and store them in the TPM. CQ-DEPEND=CL:244542 BRANCH=veyron BUG=chromium:451609 TEST=Booted Jerry. Confirmed that PCR0 contains the same value as on my vboot1 Blaze and Falco (and PCR1 contains some non-zero hash).

vboot2 abtracts tpm storage as some 'secure' space. Thus, it's firmware's responsibility to handle vboot specific operations with tpm. This CL just copies related files from vboot_reference so that we can see how code was modified in the next CL. Note rollback_index.c/h were renamed to antirollback.c/h.
