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> 2018-05-07 06:58:06 +09:00			`// SPDX-License-Identifier: GPL-2.0`
ARM: arm1176: Define arch_cpu_init() at the SoC level Commit 86c6326 "ARM: arm1176: enable instruction cache in arch_cpu_init()" defined arch_cpu_init() in a file that is shared across all arm1176 SoCs. tnetv107x already implemented this function, which caused linking to break. Move the new conflicting arch_cpu_init() into arm1176/bcm2835/init.c so that it doesn't conflict; grep indicates this function is usually defined at the SoC-level, not the CPU-level, at least for ARM.
