includes: move openssl headers to include/u-boot

2014-06-19T15:19:04+00:00

commit 18b06652cd "tools: include u-boot version of sha256.h"
unconditionally forced the sha256.h from u-boot to be used
for tools instead of the host version. This is fragile though
as it will also include the host version. Therefore move it
to include/u-boot to join u-boot/md5.h etc which were renamed
for the same reason.

hash: Use uint8_t in preference to u8

2014-06-19T15:18:55+00:00

This type is more readily available on the host compiler, so use it instead.

common: hash: zero end the string instead of the pointer

2014-06-11T20:27:05+00:00

if algo->digest_size is zero nothing is set in the str_output
buffer. An attempt is made to zero end the buffer, but the
pointer to the buffer is set to zero instead. I am unaware if
it causes any actual problems, but solves the following warning:

common/hash.c:217:13: warning: expression which evaluates to zero treated as
a null pointer constant of type 'char *' [-Wnon-literal-null-conversion]
                str_ptr = '\0';
                          ^~~~

hash: Export the function to show a hash

2014-06-11T20:25:46+00:00

This function is useful for displaying a hash value, so export it.

gen: Add progressive hash API

2014-03-21T20:39:36+00:00

Add hash_init(), hash_update() and hash_finish() to the
hash_algo struct. Add hash_lookup_algo() to look up the
struct given an algorithm name.

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.

gen: Add sha h/w acceleration to hash

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.
