2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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 <trini@konsulko.com>
2014-03-28drivers: crypto: ace_sha: add implementation of hardware based lib randPrzemyslaw Marczak
This patch adds implementation of rand library based on hardware random number generator of security subsystem in Exynos SOC. This library includes: - srand() - used for seed hardware block - rand() - returns random number - rand_r() - the same as above with given seed which depends on CONFIG_EXYNOS_ACE_SHA and CONFIG_LIB_HW_RAND.
