Christian Hohnstaedt 81bef01500 crypto: ixp4xx - Hardware crypto support for IXP4xx CPUs
Add support for the hardware crypto engine provided by the NPE C
of the Intel IXP4xx networking processor series.

Supported ciphers: des, des3, aes
and a combination of them with md5 and sha1 hmac

Kim Phillips 9c4a79653b crypto: talitos - Freescale integrated security engine (SEC) driver
Add support for the SEC available on a wide range of PowerQUICC devices,
e.g. MPC8349E, MPC8548E.

This initial version supports authenc(hmac(sha1),cbc(aes)) for use with IPsec.

Ralph Wuerthner 2f7c8bd6dc [S390] zcrypt: add support for large random numbers
This patch allows user space applications to access large amounts of
truly random data. The random data source is the build-in hardware

Herbert Xu 946fef4e14 [CRYPTO] hifn795x: Disallow built-in hifn795x when HW_RANDOM is m
Currently it is possible to select HW_RANDOM as a module and have
hifn795x built-in.  This causes a build problem because hifn795x
will then call hwrng_register which isn't built-in.

This patch introduces a new config option to control the hifn795x
RNG which lets us avoid this problem.

Herbert Xu 653ebd9c85 [CRYPTO] blkcipher: Merge ablkcipher and blkcipher into one option/module
With the impending addition of the givcipher type, both blkcipher and
ablkcipher algorithms will use it to create givcipher objects.  As such
it no longer makes sense to split the system between ablkcipher and
blkcipher.  In particular, both ablkcipher.c and blkcipher.c would need
to use the givcipher type which has to reside in ablkcipher.c since it
shares much code with it.

This patch merges the two Kconfig options as well as the modules into one.

[    6.052000] padlock: Using VIA PadLock ACE for SHA1/SHA256 algorithms.

When it's a module it isn't doing anything special, the same functionality 
can be provided in userspace by "probeall padlock padlock-aes padlock-sha" 
in modules.conf if it is required.

Starting with the z9 the CPU Cryptographic Assist Facility comes with
an integrated Pseudo Random Number Generator. The generator creates
random numbers by an algorithm similar to the ANSI X9.17 standard.
The pseudo-random numbers can be accessed via a character device driver
node called /dev/prandom. Similar to /dev/urandom any amount of bytes
can be read from the device without blocking.
