    m68knommu: add optimize memmove() function · 982cd252
    Greg Ungerer authored
    Add an m68k/coldfire optimized memmove() function for the m68knommu arch.
    This is the same function as used by m68k. Simple speed tests show this
    is faster once buffers are larger than 4 bytes, and significantly faster
    on much larger buffers (4 times faster above about 100 bytes).
    
    This also goes part of the way to fixing a regression caused by commit
    ea61bc46 ("m68k/m68knommu: merge MMU and
    non-MMU string.h"), which breaks non-coldfire non-mmu builds (which is
    the 68x328 and 68360 families). They currently have no memmove() fucntion
    defined, since there was none in the m68knommu/lib functions.
