| |
Most architectures that define CONFIG_HAVE_DMA, have implementations for both dma_alloc_attrs() and dma_free_attrs(). All achitectures that do not define CONFIG_HAVE_DMA also have both of these definitions provided by dma-mapping-broken.h.
Add default implementations for these functions on c6x.
