In linux kernel since version 2.6.24 (release Date: 2008-01-24)
Some systems accss MMC/SD cards using a SPI controller instead of
using a "native" MMC/SD controller. This has a disadvantage of

working on many systems without dedicated MMC/SD controllers.
If unsure, or if your system has no SPI master driver, say N.
