| config VBOOT2_VERIFY_FIRMWARE |
| bool "Firmware Verification with vboot2" |
| default n |
| depends on CHROMEOS && HAVE_HARD_RESET |
| help |
| Enabling VBOOT2_VERIFY_FIRMWARE will use vboot2 to verify the romstage |
| and boot loader. |
| |
| config VBOOT2_MOCK_SECDATA |
| bool "Mock secdata for firmware verification" |
| default n |
| depends on VBOOT2_VERIFY_FIRMWARE |
| help |
| Enabling VBOOT2_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 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. |
