8	help
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.

23	  Use VIA PadLock for AES algorithm.
24
25	  Available in VIA C3 and newer CPUs.
26
27	  If unsure say M. The compiled module will be
28	  called padlock-aes.ko

37	  Use VIA PadLock for SHA1/SHA256 algorithms.
38
39	  Available in VIA C7 and newer processors.

53	  Say 'Y' here to use the AMD Geode LX processor on-board AES
54	  engine for the CryptoAPI AES algorithm.
55
56	  To compile this driver as a module, choose M here: the module
57	  will be called geode-aes.

65	  Select this option if you want to use a PCI-attached cryptographic
66	  adapter like:
67	  + PCI Cryptographic Accelerator (PCICA)
68	  + PCI Cryptographic Coprocessor (PCICC)
69	  + PCI-X Cryptographic Coprocessor (PCIXCC)

77	  Select this option if you want to have a single module z90crypt.ko
78	  that contains all parts of the crypto device driver (ap bus,
79	  request router and all the card drivers).
