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

common: Make sure arch-specific map_sysmem() is defined

2015-04-18T17:11:09+00:00

In the case where the arch defines a custom map_sysmem(), make sure that
including just mapmem.h is sufficient to have these functions as they
are when the arch does not override it.

Also split the non-arch specific functions out of common.h

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.

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.

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';
