SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

Kconfig: Finish migration of hashing commands

2017-05-31T23:38:14Z

Currently these (board agnostic) commands cannot be selected using menuconfig and friends. Fix this the obvious way. As part of this, don't muddle the meaning of CONFIG_HASH_VERIFY to mean both 'hash -v' and "we have a hashing command" as this makes the Kconfig logic odd.

hash.c: Conditionally compile hash_command, static hash_show

2016-01-14T02:05:08Z

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. Signed-off-by: Tom Rini

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

2015-06-08T21:32:40Z

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 Signed-off-by: Stefan Roese Reviewed-by: Simon Glass

hash: Add function to find hash_algo struct with progressive hash

2015-01-30T00:09:59Z

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

2014-06-19T15:18:55Z

This type is more readily available on the host compiler, so use it instead. Signed-off-by: Simon Glass

hash: Export the function to show a hash

2014-06-11T20:25:46Z

This function is useful for displaying a hash value, so export it. Signed-off-by: Simon Glass

Prevent a buffer overflow in mkimage when signing with SHA256

2014-06-05T21:01:23Z

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. Signed-off-by: Michael van der Westhuizen Acked-by: Simon Glass [trini: Rework a bit so move the exportable parts of hash.h outside of !USE_HOSTCC and only need that as a new include to image.h] Signed-off-by: Tom Rini

gen: Add progressive hash API

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. Signed-off-by: Hung-ying Tyan Signed-off-by: Simon Glass Signed-off-by: Heiko Schocher Acked-by: Simon Glass
