Guennadi Liakhovetski 5f52c35529 mmc: tmio: use PIO for short transfers ... This patch allows transferring of some requests in PIO and some in DMA mode and defaults to using DMA only for transfers longer than 8 bytes. This is especially useful with SDIO, which can have lots of 2- and 4-byte transfers, creating unnecessary high overhead, when executed in DMA.
