6c3f975a4c crypto: Make Open Firmware device id constant
From: Márton Németh <nm127@freemail.hu>

The match_table field of the struct of_device_id is constant in <linux/of_platform.h>
so it is worth to make the initialization data also constant.

The semantic match that finds this kind of pattern is as follows:

305f9db22d crypto: crypto4xx - Disable SHA implementation
The crypto4xx SHA implementation keeps the hash state in the tfm
data structure.  This breaks a fundamental requirement of ahash
implementations that they must be reentrant.

This patch disables the broken implementation.

4dc10c0142 crypto: crypto4xx - Switch to new style ahash
This patch changes crypto4xx to use the new style ahash type.
In particular, we now use ahash_alg to define ahash algorithms
instead of crypto_alg.

This is achieved by introducing a union that encapsulates the
new type and the existing crypto_alg structure.  They're told
apart through a u32 field containing the type value.

6b1679f4a0 crypto: crypto4xx - Use crypto_ahash_set_reqsize
This patch makes crypto4xx use crypto_ahash_set_reqsize to avoid
accessing crypto_ahash directly.

049359d655 crypto: amcc - Add crypt4xx driver
This patch adds support for AMCC ppc4xx security device driver. This is the
initial release that includes the driver framework with AES and SHA1 algorithms
support.

The remaining algorithms will be released in the near future.
