[PATCH 0/9 v3] digest: allow multiple implementation of digest

[Jean-Christophe PLAGNIOL-VILLARD]

Hi,

	The following serie allow you to have multiple driver for
	the digest.

	This also switch the sha1 implementation to the kernel one and
	add the armv4 asm implementtion that save nearly 6KiB in a zbarebox
	lzo.


v2:
	switch sha256 and sha512 to linux implementation
	add arm sha256 asm implementation

v3:
	Fix sha256 for armv4 in a better way as discussed on ARM ML
	Only register the generic hmac one time per sha algo, as we will
	use the best sha algo at runtime
