[edk2-devel] [PATCH 3/3] Platform/RaspberryPi; Invert default Arasan, Emmc2 routing

[Jeremy Linton]

In order for the wifi to work, and the SD to run at full
speed we need to bind the sd slot to the eMMC2 controller.

Since we now have a driver for the eMMC2 controller
there isn't any reason to leave the SD card bound
to the older Arasan controller.
