crypto: crypto4xx - Disable SHA implementation
Herbert Xu [Wed, 15 Jul 2009 07:11:08 +0000 (15:11 +0800)]
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.
