2018-02-07security/vboot: overwrite existing spaces during factory init for tpm2Andrey Pronin
In TPM 2.0 case, if the factory initialization is interrupted after defining, say, the kernel tpm nvram space but before writing to this space, the following will happen upon reboot when the factory initialization will be re-attempted. Writing to this space will be skipped, and coreboot will finish the factory initialization with this space remained unwritten. At a later stage, when the rollback logic will attempt to check the version in the kernel space, it will fail (TPM2.0 returns an error when reading from unwritten spaces), and the system will go into recovery with no way out (since the kernel space will never be written). This change fixes that by always writing to the kernel, MRC hash and firmware spaces during factory initialization, even if the space already existed by that time. BUG=b:71884828 TEST=delete, define, but not write to the kernel space; trigger factory initialization; coreboot should fill the kernel space and continue booting.

2018-01-17security/vboot: Add two weak methods for vboot2Philipp Deppenwiese
In order to make VBOOT2 independent from the CHROMEOS kconfig option a weak method for get_write_protect_state and get_recovery_mode_switch() is required. Introduce a kconfig option for controlling this behaviour. This is a temporary fix and will be removed afterwards.
