+ Block ciphers: AES cipher algorithms (FIPS-197)
+
+ 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.

+ - CTR (Counter) mode (NIST SP800-38A)
+ - 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.
