+U-Boot for NanoPi-K2
+====================
+
+NanoPi-K2 is a single board computer manufactured by FriendlyElec
+with the following specifications:
+
+ - Amlogic S905 ARM Cortex-A53 quad-core SoC @ 1.5GHz
+ - ARM Mali 450 GPU
+ - 2GB DDR3 SDRAM
+ - Gigabit Ethernet
+ - HDMI 2.0 4K/60Hz display
+ - 40-pin GPIO header
+ - 4 x USB 2.0 Host, 1 x USB OTG
+ - eMMC, microSD
+ - Infrared receiver
+
+Schematics are available on the manufacturer website.
+
+Currently the u-boot port supports the following devices:
+ - serial
+ - eMMC, microSD
+ - Ethernet
+
+u-boot compilation
+==================
+
+ > export ARCH=arm
+ > export CROSS_COMPILE=aarch64-none-elf-
+ > make nanopi-k2_defconfig
+ > make
+
+Image creation
+==============
+
+Amlogic doesn't provide sources for the firmware and for tools needed
+to create the bootloader image, so it is necessary to obtain them from
+the git tree published by the board vendor:
