+
+	  Architecture: arm
+
+	  On ARM processors without the Crypto Extensions, this is the
+	  fastest AES implementation for single blocks.  For multiple
+	  blocks, the NEON bit-sliced implementation is usually faster.
+
+	  This implementation may be vulnerable to cache timing attacks,
+	  since it uses lookup tables.  However, as countermeasures it
+	  disables IRQs and preloads the tables; it is hoped this makes
+	  such attacks very difficult.

+	   - XTS (XOR Encrypt XOR with ciphertext stealing) mode (NIST SP800-38E
+	     and IEEE 1619)
+
+	  Bit sliced AES gives around 45% speedup on Cortex-A15 for CTR mode
+	  and for XTS mode encryption, CBC and XTS mode decryption speedup is
+	  around 25%. (CBC encryption speed is not affected by this driver.)
+	  This implementation does not rely on any lookup tables so it is
+	  believed to be invulnerable to cache timing attacks.
