Enabling DMA for spi-davinci isn't quite ready yet since this driver is blindly using dma_map_single() on addresses passed in. MTD seems to use vmalloc'd buffers, which cannot be passed direclty to dma_map_single(). I thinks this driver needs an update to use spi_map_buf() to be able to handle vmalloc'd buffers before always enabling DMA. Kevin
