    kbuild: move asm-offsets.c from SoC directory to arch/$(ARCH)/lib · 254d68b6
    Masahiro Yamada authored
    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.
