crypto: caam - set RDB bit in security configuration register

2013-03-22T10:13:54+00:00

This change is required for post SEC-5.0 devices which have RNG4.
Setting RDB in security configuration register allows CAAM to use the
"Random Data Buffer" to be filled by a single request. The Random Data
Buffer is large enough for ten packets to get their IVs from a single
request. If the Random Data Buffer is not enabled, then each IV causes a
separate request, and RNG4 hardware cannot keep up resulting in lower
IPSEC throughput if random IVs are used.

Drivers: crypto: remove __dev* attributes.

2013-01-03T23:57:02+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

crypto: caam - increase TRNG clocks per sample

2012-09-27T05:32:15+00:00

we need to configure the TRNG to use more clocks per sample
to handle the two back-to-back 64KiB random descriptor requests
on higher frequency P5040s.

crypto: caam - ERA retrieval and printing for SEC device

2012-07-11T03:06:11+00:00

This patch adds support for retrieving and printing of
SEC ERA information. It is useful for knowing beforehand
what features exist from the SEC point of view on a
certain SoC. Only era-s 1 to 4 are currently supported;
other eras will appear as unknown.

crypto: caam - add support for SEC v5.x RNG4

2012-06-27T06:42:06+00:00

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.

crypto: caam - assign 40-bit masks on SEC v5.0 and above

2012-06-27T06:42:06+00:00

SEC v4.x were only 36-bit, SEC v5+ are 40-bit capable.
Also set a DMA mask for any job ring devices created.

crypto: caam - add backward compatible string sec4.0

2012-03-29T08:34:57+00:00

In some device trees of previous version, there were string "fsl,sec4.0".
To be backward compatible with device trees, we have CAAM driver first
check "fsl,sec-v4.0", if it fails, then check for "fsl,sec4.0".
