* common: Make sure arch-specific map_sysmem() is definedJoe Hershberger2015-04-18-0/+1
| | | | | | | | | | | 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 Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>

* hash: Add function to find hash_algo struct with progressive hashRuchika Gupta2015-01-29-9/+24
| | | | | | | | | | | | 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.

* Fix hash verificationNikolay Dimitrov2014-12-29-4/+2
| | | | | | | | | | Fix issue in parse_verify_sum() which swaps handling of env-var and *address. Move hash_command() argc check earlier. Cosmetic change on do_hash() variable declaration. Improved help message for "hash" command. Signed-off-by: Nikolay Dimitrov <picmaster@mail.bg> Reviewed-by: Simon Glass <sjg@chromium.org>
* includes: move openssl headers to include/u-bootJeroen Hofstee2014-06-19-2/+2
| | | | | | | | | | | | 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. cc: Simon Glass <sjg@chromium.org> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
* hash: Use uint8_t in preference to u8Simon Glass2014-06-19-6/+6

* common: hash: zero end the string instead of the pointerJeroen Hofstee2014-06-11-1/+1
| | | | | | | | | | | | | | | 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'; ^~~~ cc: Simon Glass <sjg@chromium.org> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

* hash.c: Correct non-hash subcommand crc32 addr-save supportTom Rini2013-11-25-2/+2
| | | | | | | | | | | | | 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. Signed-off-by: Tom Rini <trini@ti.com>

* hash: Add a way to calculate a hash for any algortihmSimon Glass2013-05-14-0/+23
| | | | | | | | | | | 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. Signed-off-by: Simon Glass <sjg@chromium.org>

* hash: Use lower case for hash algorithm namesSimon Glass2013-02-28-5/+6
| | | | | | | | | | 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. Signed-off-by: Simon Glass <sjg@chromium.org>

* Roll crc32 into hash infrastructureSimon Glass2013-02-28-38/+80
| | | | | | | | | | | | | | | | | 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). Signed-off-by: Simon Glass <sjg@chromium.org>
* hash: Add a flag to support saving hashes in the environmentSimon Glass2013-02-28-17/+52
| | | | | | | | | 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. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add generic hash APISimon Glass2012-12-11-0/+221
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. Signed-off-by: Simon Glass <sjg@chromium.org>
