In linux kernel since version 2.6.24 (release Date: 2008-01-24)
Some systems access MMC/SD/SDIO cards using a SPI controller
instead of using a "native" MMC/SD/SDIO controller. This has a
disadvantage of being relatively high overhead, but a compensating
advantage of working on many systems without dedicated MMC/SD/SDIO
controllers.
If unsure, or if your system has no SPI master driver, say N.
