hash.c: Conditionally compile hash_command, static hash_show

2016-01-14T02:05:08+00:00

The function hash_show is now only called by hash_command, so mark it as
static (and drop from hash.h).  We only call hash_command when any of
CONFIG_CMD_CRC32, CONFIG_CMD_SHA1SUM or CONFIG_CMD_HASH are set.  Since
hash.c is linked in unconditionally we must take extra care with
functions that bring in read-only strings as these will not be
discarded.

autoboot.c: Add feature to stop autobooting via SHA256 encrypted password

2015-06-08T21:32:40+00:00

This patch adds the feature to only stop the autobooting, and therefor
boot into the U-Boot prompt, when the input string / password matches
a values that is encypted via a SHA256 hash and saved in the environment.

This feature is enabled by defined these config options:
     CONFIG_AUTOBOOT_KEYED
     CONFIG_AUTOBOOT_STOP_STR_SHA256

hash: Add function to find hash_algo struct with progressive hash

2015-01-30T00:09:59+00:00

The hash_algo structure has some implementations in which progressive hash
API's are not defined. These are basically the hardware based implementations
of SHA. An API is added to find the algo which has progressive hash API's
defined. This can then be integrated with RSA checksum library which uses
Progressive Hash API's.

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.

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.

Prevent a buffer overflow in mkimage when signing with SHA256

2014-06-05T21:01:23+00:00

Due to the FIT_MAX_HASH_LEN constant not having been updated
to support SHA256 signatures one will always see a buffer
overflow in fit_image_process_hash when signing images that
use this larger hash.  This is exposed by vboot_test.sh.

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: 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.
