Looks like an issue with SATA - not sure why. You might want to try to
disable SATA / AHCI for testing.

Take a look at arch/arm/mach-mvebu/arm64-common.c. Perhaps this code
needs some changes for CONFIG_ARMADA_A3700 similar to what is done
for CONFIG_ARMADA_8K ?

I suggest you debug in this area a bit to see, where it goes wrong.
