		This assumes that the generated image is already pre-validated.
		This is the recommended option for the initial stages of the

config ESP32S2_ESPTOOL_TARGET_SECONDARY
	bool "Application image secondary slot"
	---help---
		The application needs to confirm the generated image as valid,
		otherwise the bootloader may consider it invalid and perform the
		rollback of the update after a reset.
		This is the choice most suitable for the development and verification
		of a secure firmware update workflow.
