The TYPE tag is a 32-bit unsigned integer (uint32_t
) that, when viewed in little-endian format, states the type of firmware image the IMG2/IMG3/IMG4/IM4P file is. This value is passed to load_selected_image
and then image_load
early in the SecureROM boot process, where a non-NULL pointer check is performed.
