(not sure if you got notified off list, but fwiw the bug is apparently
resolved by upgrading to a newer release of u-boot - same version, from
u-boot 2017.03 armada v17.06 to u-boot 2017.03 armada v17.10
I have no idea what they're doing in u-boot with the memory setup but I
guess the case is closed...)
