This mostly crossports crypto/hash.[ch] from btrfs-progs. The differences are: - No blake2 support No blake2 related library in U-Boot yet. - Use uboot xxhash/sha256 directly No need to implement the code as U-Boot has already provided the interface. This adds the support for the following csums: - SHA256 - XXHASH Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: Marek Behún <marek.behun@nic.cz>
