From 323a6bf1d6f4ec7907d9d8aacb4ae9590f755dda Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 13 Sep 2012 23:00:49 +0000 Subject: powerpc: Add a powerpc implementation of SHA-1 This patch adds a crypto driver which provides a powerpc accelerated implementation of SHA-1, accelerated in that it is written in asm. Original patch by Paul, minor fixups for upstream by moi. Lightly tested on 64-bit with the test program here: http://michael.ellerman.id.au/files/junkcode/sha1test.c Seems to work, and is "not slower" than the generic version. Needs testing on 32-bit.
