RFC4122 defines that fields are stored in network order (big endian), but TF-A stores them in machine order (little endian by default in TF-A). We cannot change the future UUIDs that are already generated, but we can store all the bytes using arrays and modify fiptool to generate the UUIDs with the correct byte order.
