    m68k: make support for FPU hardware configurable · 9657a872
    Greg Ungerer authored
    The classic m68k code has always supported an FPU (although it may have
    been a software emulated one). The non-MMU m68k code has never supported FPU
    hardware. To help in merging common code create a configation setting that
    signifies if we are builing in FPU support or not.
    This switch, CONFIG_FPU, is set as per the current use cases. So it is
    always enabled if CONFIG_MMU is set, and disabled otherwise. With a little
    extra code it will be possible to disable it on the classic m68k platforms
    as well, and to enable it on non-MMU platforms that do have hardware FPU.
