sys/dev/sdmmc : sdmmc_io.c sdmmc_ioreg.h
Log message:
So far the SDIO stack issued one transfer for every 64 byte to be
copied. This severely limits the speed over the bus. By using
block mode we can issue block-sized transfers, which bumps the
transfer size to at least 512 bytes. By using multi-block mode
we can copy up to 511 blocks per transfer.
