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.

arc: add architecture header files These are header files used by ARC700 architecture. Also note that "arch-arc700/hardware.h" is only required for compilation of "designware_i2c" driver which refers to "asm/arch/hardware.h". It would be good to fix mentioned driver sometime soon but it will cause changes in ARM board configs that use "designware_i2c".

arc: Use the generic bitops headers The generic bitops headers are required when calling logarithmic functions, such as ilog2(). Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> 2015-11-05 14:43:36 +00:00			`#include <asm-generic/bitops/fls.h>`
