+config VBOOT_VBNV_OFFSET
+	hex
+	default 0x26
+	depends on PC80_SYSTEM
+	help
+	  CMOS offset for VbNv data. This value must match cmos.layout
+	  in the mainboard directory, minus 14 bytes for the RTC.
+
+config VBOOT_VBNV_CMOS
+	bool "Vboot non-volatile storage in CMOS."
+	default n
+	help
+	  VBNV is stored in CMOS
+
+config VBOOT_VBNV_CMOS_BACKUP_TO_FLASH
+	bool "Back up Vboot non-volatile storage from CMOS to flash."
+	default n
+	depends on VBOOT_VBNV_CMOS
+	help
+	  Vboot non-volatile storage data will be backed up from CMOS to flash
+	  and restored from flash if the CMOS is invalid due to power loss.
+
+config VBOOT_VBNV_EC
+	bool "Vboot non-volatile storage in EC."
+	default n
+	help
+	  VBNV is stored in EC
+
+config VBOOT_VBNV_FLASH
+	def_bool n
+	help
+	  VBNV is stored in flash storage
+
+config VBOOT_STARTS_IN_BOOTBLOCK
+	bool "Vboot starts verifying in bootblock"
+	default n
+	depends on VBOOT
+	help
+	  Firmware verification happens during or at the end of bootblock.
+
+config VBOOT_STARTS_IN_ROMSTAGE
+	bool "Vboot starts verifying in romstage"
+	default n
+	depends on VBOOT && !VBOOT_STARTS_IN_BOOTBLOCK
+	help
+	  Firmware verification happens during or at the end of romstage.
+
+config VBOOT_MOCK_SECDATA
+	bool "Mock secdata for firmware verification"
+	default n
+	depends on VBOOT
+	help
+	  Enabling VBOOT_MOCK_SECDATA will mock secdata for the firmware
+	  verification to avoid access to a secdata storage (typically TPM).
+	  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 VBOOT_DISABLE_DEV_ON_RECOVERY
+	bool "Disable dev mode on recovery requests"
+	default n
+	depends on VBOOT
+	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.
+
+config SEPARATE_VERSTAGE
+	bool "Vboot verification is built into a separate stage"
+	default n
+	depends on VBOOT
+
+config RETURN_FROM_VERSTAGE
+	bool "The separate verification stage returns to its caller"
+	default n
+	depends on SEPARATE_VERSTAGE
+	help
+	  If this is set, the verstage returns back to the calling stage instead
+	  of exiting to the succeeding stage so that the verstage space can be
+	  reused by the succeeding stage. This is useful if a ram space is too
+	  small to fit both the verstage and the succeeding stage.
+
+config CHIPSET_PROVIDES_VERSTAGE_MAIN_SYMBOL
+	bool "The chipset provides the main() entry point for verstage"
+	default n
+	depends on SEPARATE_VERSTAGE
+	help
+	  The chipset code provides their own main() entry point.
+
+config VBOOT_DYNAMIC_WORK_BUFFER
+	bool "Vboot's work buffer is dynamically allocated."
+	default y if ARCH_ROMSTAGE_X86_32 && !SEPARATE_VERSTAGE
+	default n
+	depends on VBOOT
+	help
+	  This option is used when there isn't enough pre-main memory
+	  ram to allocate the vboot work buffer. That means vboot verification
+	  is after memory init and requires main memory to back the work
+	  buffer.
+
+config VBOOT_SAVE_RECOVERY_REASON_ON_REBOOT
+	bool
+	default n
+	depends on VBOOT
+	help
+	  This option ensures that the recovery request is not lost because of
+	  reboots caused after vboot verification is run. e.g. reboots caused by
+	  FSP components on Intel platforms.
+
+config VBOOT_OPROM_MATTERS
+	bool "Video option ROM matters (= can skip display init)"
+	default n
+	depends on VBOOT
+	help
+	  Set this option to indicate to vboot that this platform will skip its
+	  display initialization on a normal (non-recovery, non-developer) boot.
+	  Vboot calls this "oprom matters" because on x86 devices this
+	  traditionally meant that the video option ROM will not be loaded, but
+	  it works functionally the same for other platforms that can skip their
+	  native display initialization code instead.
+
+config VBOOT
+	bool "Verify firmware with vboot."
+	default n
+	depends on HAVE_HARD_RESET
+	help
+	  Enabling VBOOT will use vboot to verify the components of the firmware
+	  (stages, payload, etc).
