The SEC4 supercedes the SEC2.x/3.x as Freescale's
Integrated Security Engine. Its programming model is
incompatible with all prior versions of the SEC (talitos).
The SEC4 is also known as the Cryptographic Accelerator
and Assurance Module (CAAM); this driver is named caam.
This initial submission does not include support for Data Path
mode operation - AEAD descriptors are submitted via the job
ring interface, while the Queue Interface (QI) is enabled
for use by others. Only AEAD algorithms are implemented
at this time, for use with IPsec.
Many thanks to the Freescale STC team for their contributions
to this driver.

This patch converts the padlock-sha implementation to shash.
In doing so the existing mechanism of storing the data until
final is no longer viable as we do not have a way of allocating
data in crypto_shash_init and then reliably freeing it.
This is just as well because a better way of handling the problem
is to hash everything but the last chunk using normal sha code
and then provide the intermediate result to the padlock device.
This is good enough because the primary application of padlock-sha
is IPsec and there the data is laid out in the form of an hmac
header followed by the rest of the packet. In essence we can
provide all the data to the padlock as the hmac header only needs
to be hashed once.

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.

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.

random numbers by an algorithm similar to the ANSI X9.17 standard.
