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

ARM: uniphier: rework existing DDR PHY code to reuse for LD11 SoC The DDR PHY register view of LD11 is slightly different from that of LD4/Pro4/sLD8, but it will be possible to share the register macros (and I want to re-use as much code as possible). Change the code in the more flexible form. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> 2016-10-27 14:47:07 +00:00			`/*`

arm: uniphier: fix header inclusion guard It seems like the header inclusion guard for some Uniphier DDR PHY header was misspelled. Make the preprocessor symbol for the #ifndef and #define lines the same, so that the double inclusion protection works as expected.
