-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:

-U-Boot for ODROID-C2
-====================
-
-ODROID-C2 is a single board computer manufactured by Hardkernel
-Co. Ltd with the following specifications:
-
- - Amlogic S905 ARM Cortex-A53 quad-core SoC @ 2GHz
- - 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
- - I2C
- - Regulators
- - Reset controller
- - Clock controller
- - ADC
-
-u-boot compilation
-==================

- > export ARCH=arm
- > export CROSS_COMPILE=aarch64-none-elf-
- > make odroid-c2_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:

+U-Boot for LibreTech AC
+=======================
+
+LibreTech AC is a single board computer manufactured by Libre Technology
+with the following specifications:
+
+ - Amlogic S805X ARM Cortex-A53 quad-core SoC @ 1.2GHz
+ - ARM Mali 450 GPU
+ - 512MiB DDR4 SDRAM
+ - 10/100 Ethernet
+ - HDMI 2.0 4K/60Hz display
+ - 40-pin GPIO header
+ - 4 x USB 2.0 Host
+ - eMMC, SPI NOR Flash
+ - Infrared receiver
+
+Schematics are available on the manufacturer website.
+
+Currently the U-Boot port supports the following devices:
+ - serial
+ - eMMC
+ - Ethernet
+ - USB
+
+U-Boot compilation
+==================
+
+ > export ARCH=arm
+ > export CROSS_COMPILE=aarch64-none-elf-
+ > make libretech-ac_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:

+ The value of the firmware-loader property should be set with phandle
