Blackfin: only flag L1 instruction for DMA memcpy The performance difference from doing an 8 bit DMA memcpy vs an optimized core memcpy can be pretty big when you add in the overhead of setting up the MDMA registers, cache flushes, etc... So only use dma_memcpy() when we actually require it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
