The SDIO interface is available either on pins MPP9/11/12/13/14/15 or
|
|
MPP47/48/49/50/51/52 on the Armada 370. Even though all combinations
|
|
are potentially possible, those two muxing options are the most
|
|
probable ones, so we provide those at the SoC level .dtsi file.
|
|
|
|
In practice, in turns out the Armada 370 DB board uses the former,
|
|
while the Armada 370 Mirabox uses the latter.
