+U-Boot for Khadas VIM3
+======================
+
+Khadas VIM3 is a single board computer manufactured by Shenzhen Wesion
+Technology Co., Ltd. with the following specifications:
+
+ - Amlogic A311D Arm Cortex-A53 dual-core + Cortex-A73 quad-core SoC
+ - 4GB LPDDR4 SDRAM
+ - Gigabit Ethernet
+ - HDMI 2.1 display
+ - 40-pin GPIO header
+ - 1 x USB 3.0 Host, 1 x USB 2.0 Host
+ - eMMC, microSD
+ - M.2
+ - Infrared receiver
+
+Schematics are available on the manufacturer website.
+
+Currently the U-Boot port supports the following devices:
+ - serial
+ - eMMC, microSD
+ - Ethernet
+ - I2C
+ - Regulators
+ - Reset controller
+ - Clock controller
+ - ADC
+
+u-boot compilation
+==================
+

+ > export CROSS_COMPILE=aarch64-none-elf-
+ > make khadas-vim3_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:
+
