From 0777e3e1723f69276136140209c11deeecb7c6dc Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Tue, 5 Aug 2014 21:15:19 +0100 Subject: ARM: 8125/1: crypto: enable NEON SHA-1 for big endian This tweaks the SHA-1 NEON code slightly so it works correctly under big endian, and removes the Kconfig condition preventing it from being selected if CONFIG_CPU_BIG_ENDIAN is set.

As this is an inappropriate use of the kernel crypto API to try to generate random numbers before initialization, checks verifying for an initialized DRBG have been removed in previous patches. Now, the drbg_healthcheck test must also be removed. Changes V2: Added patch marker to email subject line.
