hash.c: Correct non-hash subcommand crc32 addr-save support

2013-11-25T15:41:51+00:00

In the case of not having CONFIG_CMD_HASH but having CONFIG_CMD_CRC32
enabled (and not CONFIG_CRC32_VERIFY), we end up in this part of the
code path on hash_command().  However, we will only have exactly 3 args
here, and 3 > 3 is false, and we will not try and store the hash at the
address given as arg #3.  The next problem however is that we've been
moving argv around so the third value is now in argv[0] not argv[3].

Confirmed on AM335x Beaglebone White.

hash: Add a way to calculate a hash for any algortihm

2013-05-14T19:37:24+00:00

Rather than needing to call one of many hashing algorithms in U-Boot,
provide a function hash_block() which handles this, and can support all
available hash algorithms.

Once we have md5 supported within hashing, we can use this function in
the FIT image code.

to test SHA 256 hash algorithm.

hash: Use lower case for hash algorithm names

2013-03-01T03:49:13+00:00

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.

sandbox: Allow hash functions to work correctly

Use map_sysmem() so that hashing is possible on sandbox.

Roll crc32 into hash infrastructure

2013-03-01T03:09:23+00:00

Add the CRC32 algorithm to the list of available hashes, and make
the crc32 command use hash_command(). Add a new crc32_wd_buf() to
make this possible, which puts its result in a buffer rather than
returning it as a 32-bit value.

Note: For some boards the hash command is not enabled, neither
are sha1, sha256 or the verify option. In this case the full
hash implementation adds about 500 bytes of overhead. So as a
special case, we use #ifdef to select very simple bahaviour in
that case. The justification for this is that it is currently
a very common case (virtually all boards enable crc32 but only
some enable more advanced features).

hash: Add a flag to support saving hashes in the environment

2013-03-01T03:09:23+00:00

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.

Add generic hash API

2012-12-11T20:17:34+00:00

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.
