   9           Some VIA processors come with an integrated crypto engine
  10           (so called VIA PadLock ACE, Advanced Cryptography Engine)
  11           that provides instructions for very fast cryptographic
  12           operations with supported algorithms.
  13
  14           The instructions are used only when the CPU supports them.
  15           Otherwise software encryption is used.
  16
  17           Selecting M for this option will compile a helper module
  18           padlock.ko that should autoload all below configured
  19           algorithms. Don't worry if your hardware does not support
  20           some or all of them. In such case padlock.ko will
  21           simply write a single line into the kernel log informing
  22           about its failure but everything will keep working fine.
  23
  24           If you are unsure, say M. The compiled module will be
  25           called padlock.ko

  33           Use VIA PadLock for AES algorithm.

  35           Available in VIA C3 and newer CPUs.
  36
  37           If unsure say M. The compiled module will be

  48
  49           Available in VIA C7 and newer processors.
  50
  51           If unsure say M. The compiled module will be

  63           Say 'Y' here to use the AMD Geode LX processor on-board AES
  64           engine for the CryptoAPI AES alogrithm.
  65
  66           To compile this driver as a module, choose M here: the module
  67           will be called geode-aes.
