Changes in relation to FriendlyARM's U-Boot nanopi2-v2016.01: - DM_VIDEO support (display_dev.h). - boot0.h added, handles NSIH --> tools/nexell obsolete. - gpio.h: Include-path to errno.h changed.

Changes in relation to FriendlyARM's U-Boot nanopi2-v2016.01: - i2c/nx_i2c.c: Some adaptions mainly because of changes in "struct udevice". - mmc: nexell_dw_mmc.c changed to nexell_dw_mmc_dm.c (switched to DM).

Changes in relation to FriendlyARM's U-Boot nanopi2-v2016.01: - SPL not supported yet --> no spl-dir in arch/arm/cpu/armv7/s5p4418/. Appropriate line in Makefile removed. - cpu.c: '#include <cpu_func.h>' added. - arch/arm/cpu/armv7/s5p4418/u-boot.lds removed, is not required anylonger. - s5p4418.dtsi: '#include "../../../include/generated/autoconf.h"' removed, is not necessary, error at out-of-tree building. '#ifdef CONFIG_CPU_NXP4330'-blocks (2x) removed. Some minor changes regarding mmc. 'u-boot,dm-pre-reloc' added to dp0 because of added DM_VIDEO support. - board/s5p4418/ renamed to board/friendlyarm/ - All s5p4418-boards except nanopi2 removed because there is no possibility to test the other boards. - Kconfig: Changes to have a structure like mach-bcm283x (RaspberryPi), e.g. "config ..." entries moved from/to other Kconfig. - "CONFIG_" removed from several s5p4418/nanopi2 specific defines because the appropriate values do not need to be configurable. - nanopi2/board.c: All getenv(), getenv_ulong(), setenv() and saveenv() renamed to env_get(), env_get_ulong(), env_set() and env_save(), respectively. MACH_TYPE_S5P4418 is not defined anymore, therefore appropriate code removed (not necessary for DT-kernels). - nanopi2/onewire.c: All crc8() renamed to crc8_ow() because crc8() is already defined in lib/crc8.c (with different parameters).

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.
