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. Signed-off-by: Tom Rini <trini@konsulko.com>

ARM: uniphier: move PLL init code to U-Boot proper where possible The PLL for the DRAM interface must be initialized in SPL, but the others can be delayed until U-Boot proper. Move them from SPL to U-Boot proper to save the precious SPL memory footprint. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
