U-Boot has supported two kinds of asm-offsets.h. One is generic for all architectures and its source is located at ./lib/asm-offsets.c. The other is SoC specific and its source is under SoC directory. The problem here is that only boards with SoC directory can use the asm-offsets infrastructure. Putting asm-offsets.c right under CPU directory does not work. Now a new demand is coming. PowerPC folks want to use asm-offsets. But no PowerPC boards have SoC directory. It seems inconsistent that some boards add asm-offsets.c to SoC directoreis and some to CPU directories. It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib. This commit merges asm-offsets.c under SoC directories into arch/$(ARCH)/lib/asm-offsets.c. By the way, I doubt the necessity of some entries in asm-offsets.c. I am leaving refactoring to the board maintainers. Please check "TODO" in the comment blocks in arch/{arm,nds32}/lib/asm-offsets.c.
