This option is selected by drivers running on big endian hosts
|

and performing I/O to a SDHCI controller through a bus that
|
|
implements a hardware byte swapper using a 32-bit datum.
|
|
This endian mapping mode is called "data invariance" and

has the effect of scrambling the addresses and formats of data
|
|
accessed in sizes other than the datum size.

proprietary controller is unnecessary because the SDHCI driver

supports MMC cards on the SD controller, but if it is not
