/* Tables are assembled using little-endian byte order, including the
 * pre-rotated variants. Generated by aesdata.c.
 *
 * Note that AES is byte order agnostic, we only need to be consistent
 * and use the same byteorder when processing key, cleartext and
 * ciphertext bytes.
 *
 * Little-endian means that the first row of the AES state arrays
 * occupy the least significant byte of the words, which is also
 * consistent with the row numbering. */
