* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-075-11/+5
| | | | | | | | | | | | | | | | | | | | 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>
* cmd_dhry.c: Use lldiv for vax_mips calculation as wellTom Rini2016-03-171-1/+1
| | | | | | | | | | Since dhry_per_sec is a u64 we must also use lldiv here when working with it. Otherwise: ../lib/dhry/cmd_dhry.c:(.text.do_dhry+0xd8): undefined reference to `__udivdi3' On some platforms. Signed-off-by: Tom Rini <trini@konsulko.com>
* dhry: Correct dhrystone calculation for fast machinesSimon Glass2016-03-171-3/+5
| | | | | | | At present samus reports about 5600 DMIPS. With the default iteration count this is OK, but if 10 million runs are performed it overflows. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add a dhrystone benchmark commandSimon Glass2015-07-216-0/+1128
Drystone provides a convenient sanity check that the CPU is running at full speed. Add this as a command which can be enabled as needed. Note: I investigated using Coremark for this but there was a license agreement and I could not work out if it was GPL-compatible. Signed-off-by: Simon Glass <sjg@chromium.org>
