-- Hashing support:
- CONFIG_CMD_HASH
-
- This enables a generic 'hash' command which can produce
- hashes / digests from a few algorithms (e.g. SHA1, SHA256).
-
- CONFIG_HASH_VERIFY
-
- Enable the hash verify command (hash -v). This adds to code
- size a little.
-
- CONFIG_SHA1 - This option enables support of hashing using SHA1
- algorithm. The hash is calculated in software.
- CONFIG_SHA256 - This option enables support of hashing using
- SHA256 algorithm. The hash is calculated in software.
- CONFIG_SHA_HW_ACCEL - This option enables hardware acceleration
- for SHA1/SHA256 hashing.
- This affects the 'hash' command and also the
- hash_lookup_algo() function.
- CONFIG_SHA_PROG_HW_ACCEL - This option enables
- hardware-acceleration for SHA1/SHA256 progressive hashing.
- Data can be streamed in a block at a time and the hashing
- is performed in hardware.
-
- Note: There is also a sha1sum command, which should perhaps
- be deprecated in favour of 'hash sha1'.
-
-- Freescale i.MX specific commands:
- CONFIG_CMD_HDMIDETECT
- This enables 'hdmidet' command which returns true if an
- HDMI monitor is detected. This command is i.MX 6 specific.
