* minor - The MMC/SD minor device number. The MMC/SD device will be
* registered as /dev/mmcsdN where N is the minor number
* dev - And instance of an MMC/SD interface. The MMC/SD hardware should
* be initialized and ready to use.

* slotno - The slot number to use. This is only meaningful for architectures
* that support multiple MMC/SD slots. This value must be in the range
* {0, ..., CONFIG_MMCSD_NSLOTS}.
* spi - And instance of an SPI interface obtained by called
* up_spiinitialize() with the appropriate port number (see spi.h)
