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. Is is compared with the second parameter of image_load (register r1[1]). If it does not match, image_load will fail and the image will not be loaded. If 0 is passed in r1, then the check is skipped.
