The 2835 has two SD controllers:  The Arasan SDHCI controller (supported
by the iproc driver) and a custom SD controller.  This patch adds a
driver for the custom SD controller.

The custom controller runs faster, and driving the sdcard with the
custom controller also allows to drive the rpi3 wifi with the iproc
driver.

I don't understand this relationship. Is this somewhat configurable in runtime?

Is the WIFI module a removable SDIO card? So you can decide which
controller that is best suited to use? No?

Kind regards
