Guennadi Liakhovetski 93173054f2 mmc: tmio_mmc: implement a bounce buffer for unaligned DMA ... For example, with SDIO WLAN cards, some transfers happen with buffers at odd addresses, whereas the SH-Mobile DMA engine requires even addresses for SDHI. This patch extends the tmio driver with a bounce buffer, that is used for single entry scatter-gather lists both for sending and receiving. If we ever encounter unaligned transfers with multi-element sg lists, this patch will have to be extended. For now it just falls back to PIO in this and other unsupported cases.
