![]() DMA is always used in mmc driver. So the buffer address should always follow the DMA limitation. There're same requirement in mmc_read_blocks()/mmc_write_blocks() on parameter buf. Since parameter buf comes from io_block driver, it's already handled in io_block driver. At here, just make the minimum address alignment on 16 chars.
