crypto: caam - FIX RNG init for RNG greater than equal to 4

2013-05-14T02:14:51+00:00

For SEC including a RNG block version >= 4, special initialization must occur before any descriptor that uses RNG block can be submitted. This initialization is required not only for SEC with version greater than 5.0, but for SEC with RNG version >=4. There may be a case where RNG has already been instantiated by u-boot or boot ROM code.In such SoCs, if RNG is initialized again SEC would returns "Instantiation error". Hence, the initialization status of RNG4 should be also checked before doing RNG init.

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. Cc: Bill Pemberton Cc: Herbert Xu Cc: "David S.

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. Signed-off-by: Kim Phillips Signed-off-by: Herbert Xu

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.

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". Signed-off-by: Shengzhou Liu Acked-by: Kim Phillips Signed-off-by: Herbert Xu
