Actually, I meant if the use of line above with CROS_GPIO_VIRTUAL was still valid, I can see recovery_mode_switch filled in vboot context, and entry in CRHW.GPIO appears to be unusable as it does not store the state.

As for WP, I do not see VBSD_BOOT_FIRMWARE_WP_ENABLED being set anywhere, and only mrc_cache code calls get_write_protect_state().
