NULL, 0 } fails on Blackfin Fix a problem reported in the forums - libstdc++ can call writev with an iovec containing { NULL, 0 }, which works fine on i686-linux, but fails on Blackfin.

2007-10-10Blackfin arch: flush/inv the correct range when using write back cache and ↵Michael Hennerich
fix bugs find by dmacopy - flush/inv the correct range - dmacopy test failed when policy is write_back - invalidate before dma http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3367 It's the cache invalidate what is causing the issue. There is no invalidate only instruction it's always: FLUSHINV So when we "invalidate" after the DMA we might (do) overwrite freshly dma'ed data by dirty Cache WB content. Fixed by moving the "invalidate" at the beginning of dma_memcpy. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>
