ACE H/W acceleration support is added to hash which can be used to test SHA 256 hash algorithm.
Tested with command "hash sha256 0x40008000 0x2B 0x40009000". Used mm and md to write a standard string to memory location 0x40008000 and ran the above command to verify the output.

Changes since v1: - Added sha256 support to "hash" command instead of new sha256 command.
Changes sice v2: - Added new nodes for SHA1 and SHA256 in struct hash_algo for the case when ACE is enabled. - Added new declaration for function pointer hash_func_ws with different return type.
Changes sice v3: - Changed command names to lower case in algo struct. - Added generic ace_sha config.

This should be CHUNKSZ_SHA1 I think. You can't reuse this field for anything you want :-)

Similar here.
