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>

MPC512x: remove include/mpc512x.h Move needed definitions (register descriptions etc.) from include/mpc512x.h into include/asm-ppc/immap_512x.h. Instead of using a #define'd register offset, use a function that provides the PATA controller's base address. All the rest of include/mpc512x.h are register offset definitions which can be eliminated by proper use of C structures. There are only a few register offsets remaining that are needed in cpu/mpc512x/start.S; for these we provide cpu/mpc512x/asm-offsets.h which is intended as a temporary workaround only. In a later patch this file will be removed, too, and then auto-generated from the respective C structs. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: John Rigby <jcrigby@gmail.com>

Make include/common.h usable by assembler code Commit 70ebf316 factored out the ROUND() macro into include/common.h, not realizing that the primary use of this macro on AT91 systems was in start.S where common.h was not included, and could not be included because it contains a lot of C code which the assembler doesn't understand. This patch wraps such code in common.h in a "#ifndef __ASSEMBLY__" construct, and then adds an include to cpu/arm926ejs/start.S thus solving the problem. Signed-off-by: Wolfgang Denk <wd@denx.de>

include: move various macros to include/linux/kernel.h U-Boot has imported various utility macros from Linux scattering them to various places without consistency. In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN, container_of, DIV_ROUND_UP, etc. In include/linux/compat.h are min_t, max_t, round_up, round_down, etc. We also have duplicated defines of min_t in some *.c files. Moreover, we are suffering from too cluttered include/common.h. This commit moves various macros that originate in include/linux/kernel.h of Linux to their original position. Note: This commit simply moves the macros; the macros roundup, min, max, min2, max3, ARRAY_SIZE are different from those of Linux at this point.

move UL() macro from armv8/mmu.h into common.h The UL() macro is pretty useful in sharing constants between assembly and C files while still being able to specify a type for C. Move the macro from an armv8 specific header into a common header file to be able to use it by arm code (for instance) as well.
