Rather than use strcasecmp() in the hash algorithm search, require the caller to do this first. Most of U-Boot can use lower case anyway, and the hash command can convert to lower case before calling hash_command(). This saves needing strcasecmp() for boards that use hashing but not the hash command. Signed-off-by: Simon Glass <sjg@chromium.org>
