2018-05-03security/vboot: make vboot starts in bootblock depend on c envAaron Durbin
coreboot on skylake originally did ship with romcc bootblock and verstage running after it. However, that configuration makes boot flows very complicated. No platform in the current code base uses this combination. Make VBOOT_STARTS_IN_BOOTBLOCK depend on C_ENVIRONMENT_BOOTBLOCK.

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.
