(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...) -- Asmadeus | Dominique Martinet
