All operations for a secdata storage will be successful. This option can be used during development when a TPM is not present or broken. THIS SHOULD NOT BE LEFT ON FOR PRODUCTION DEVICES. config RETURN_FROM_VERSTAGE bool "return from verstage" default n depends on VBOOT2_VERIFY_FIRMWARE help If this is set, the verstage returns back to the bootblock instead of exits to the romstage so that the verstage space can be reused by the romstage. Useful if a ram space is too small to fit both the verstage and the romstage. config VBOOT_ROMSTAGE_INDEX hex default 2 depends on VBOOT2_VERIFY_FIRMWARE help This is the index of the romstage component in the verified firmware block. config VBOOT_DISABLE_DEV_ON_RECOVERY bool "Disable dev mode on recovery requests" default n depends on VBOOT2_VERIFY_FIRMWARE help When this option is enabled, the Chrome OS device leaves the developer mode as soon as recovery request is detected. This is handy on embedded devices with limited input capabilities.
