security/vboot: Add support for GSCVD (Google "RO verification")
This patch adds a new CONFIG_VBOOT_GSCVD option that will be enabled by
default for TPM_GOOGLE_TI50 devices. It makes the build system run the
`futility gscvd` command to create a GSCVD (GSC verification data) which
signs the CBFS trust anchor (bootblock and GBB). In order for this to
work, boards will need to have an RO_GSCVD section in their FMAP, and
production boards should override the CONFIG_VBOOT_GSC_BOARD_ID option
with the correct ID for each variant.
