This patch breaks down sdhci-of into a core portion and a eSDHC portion, clearing the path to easily support additional hardware using the same OF driver.

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.
