Say 'y' here if the MCI framework should probe for attached MCI cards

environment (for example on systems where the MCI card is the sole

bootmedia). Otherwise probing run on demand with "mci*.probe=1"

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.
