Changes in relation to FriendlyARM's U-Boot nanopi2-v2016.01: - Configuration changed, mainly several "CONFIG_..." moved from s5p4418_nanopi2.h to s5p4418_nanopi2_defconfig. - s5p4418_nanopi2.h: "CONFIG_" removed from several s5p4418/nanopi2 specific defines because the appropriate values do not need to be configurable.
