[ARM] 2930/1: optimized sha1 implementation for ARM
Patch from Nicolas Pitre
Here's an ARM assembly SHA1 implementation to replace the default C
version. It is approximately 50% faster than the generic C version. On
an XScale processor running at 400MHz:
generic C version: 9.8 MB/s
my version: 14.5 MB/s
This code is useful to quite a few callers in the tree:
crypto/sha1.c: sha_transform(sctx->state, sctx->buffer, temp);
crypto/sha1.c: sha_transform(sctx->state, &data[i], temp);
drivers/char/random.c: sha_transform(buf, (__u8 *)r->pool+i, buf + 5);
drivers/char/random.c: sha_transform(buf, (__u8 *)data, buf + 5);
net/ipv4/syncookies.c: sha_transform(tmp + 16, (__u8 *)tmp, tmp + 16 + 5);
Signed-off-by: Nicolas Pitre <nico@cam.org>
Seems to work fine on big-endian as well.
