Simon Glass	d5b76673a5	hash: Add a flag to support saving hashes in the environment ... Some hashing commands permit saving the hash in an environment variable, and verifying a hash from there. But the crc32 command does not support this. In order to permit crc32 to use the generic hashing infrastructure, add a flag to select which behaviour to use.

Simon Glass	460408ef9a	Add generic hash API ... We have a SHA1 command and want to add a SHA256 command also. Instead of duplicating the code, create a generic hash API which can process commands for different algorithms. Signed-off-by: Simon Glass <sjg@chromium.org>	2012-12-11 13:17:34 -07:00
