Sat Mar 28 10:43:56 CET 2020
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 and USB related
configs removed because USB is not supported yet.
- s5p4418_nanopi2.h: "CONFIG_" removed from several s5p4418/nanopi2
specific defines because the appropriate values do not need to be
configurable.

Changes in v2:
- USB related configs removed because USB is not supported yet.
- CONFIG_CMD_MEMTEST moved from s5p4418_nanopi2.h to
s5p4418_nanopi2_defconfig.
- MAINTAINERS: "F: drivers/pwm/pwm-nexell*" deleted because
arch/arm/cpu/armv7/s5p-common/pwm.c is used now. Furthermore double
line "F: drivers/video/nexell/" deleted.

+Summary
+=======
+
+This README is about U-Boot support for SAMSUNG's/NEXELL's ARM Cortex-A9 based
+S5P4418 SoC. It is based on FriendlyARM's U-Boot v2016.01 for the NanoPi2
+(and other) boards [1].
+
+Currently the following boards are supported:
+
+* FriendlyArm NanoPi2 [2]
+* FriendlyArm NanoPC-T2 [3]
+
+
+Build
+=====
+
+* NanoPi2 and NanoPC-T2
+
+make s5p4418_nanopi2_defconfig
+make
+
+
+Installation
+============
+
+- Download Official-ROMs-SDCard-20190718.7z from [4] (images files for android,
+ friendlyCore and LUbuntu)
+- Use s5p4418-sd-lubuntu-desktop-xenial-4.4-armhf-20190718.img to make a SD-card
+- Use dd in the directory where U-Boot has been built to update U-Boot:
+ (replace <SD-card> with the device used for the SD-card, e.g. sdc)
+ sudo dd seek=3841 if=u-boot.bin of=/dev/<SD-card>
+- Boot the board from this SD-card
+
+The source code for (the used?) LUbuntu 16.04 can be found at [5].
