Kim Phillips 96aef9a8ba crypto: caam - static constify error data
checkstack reports report_deco_status(), report_ccb_status() as
particularly excessive stack users.  Move their lookup tables
off the stack and put them in .rodata.

Kim Phillips 281922a1d4 crypto: caam - add support for SEC v5.x RNG4
The SEC v4.x' RNGB h/w block self-initialized.  RNG4, available
on SEC versions 5 and beyond, is based on a different standard
that requires manual initialization.

Also update any new errors From the SEC v5.2 reference manual:
The SEC v5.2's RNG4 unit reuses some error IDs, thus the addition
of rng_err_id_list over the CHA-independent err_id_list.

Dan Carpenter 6d00376ad1 crypto: caam - ARRAY_SIZE() vs sizeof()
ARRAY_SIZE() was intended here instead of sizeof().  sizeof() is four
times larger than ARRAY_SIZE().  outstr is normally 256 chars so 
printing garbage to it could overfill the buffer and corrupt memory.

Kim Phillips 8e8ec596e6 crypto: caam - Add support for the Freescale SEC4/CAAM
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.
