+U-Boot for Beelink GT-King
+==========================
+
+The Shenzen AZW (Beelink) GT-King is based on the Amlogic W400 reference
+board with an S922X-H chip.
+
+- 4GB LPDDR4 RAM
+- 64GB eMMC storage
+- 10/100/1000 Base-T Ethernet
+- AP6356S Wireless (802.11 a/b/g/n/ac, BT 4.1)
+- HDMI 2.1 video
+- S/PDIF optical output
+- Analogue audio output
+- 1x USB 2.0 port
+- 2x USB 3.0 ports
+- IR receiver
+- 1x micro SD card slot
+
+Beelink do not provide public schematics, but have been willing
+to share them with known distro developers on request.

+
+Image creation
+--------------
+
+Amlogic does not provide sources for the firmware and for tools needed
+to create the bootloader image. Beelink have provided the Amlogic "SDK"
+in their forums, but the u-boot sources included result in 2GB RAM being
+detected. The following FIPs were generated with newer private sources
+and give correct (4GB) RAM detection:
+
+https://github.com/LibreELEC/amlogic-boot-fip/tree/master/beelink-s922x
+
+NB: Beelink use a common board config for GT-King, GT-King Pro and the
+GS-King-X model, hence the "beelink-s922x" name.

+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.
+
+PCIe Setup
+----------
+The VIM3 on-board  MCU can mux the PCIe/USB3.0 shared differential
+lines using a FUSB340TMX USB 3.1 SuperSpeed Data Switch between
+an USB3.0 Type A connector and a M.2 Key M slot.
+The PHY driving these differential lines is shared between
+the USB3.0 controller and the PCIe Controller, thus only
+a single controller can use it.
+
+To setup for PCIe, run the following commands from U-Boot:
+
+.. code-block:: none
+
+    i2c dev i2c@5000
+    i2c mw 0x18 0x33 1
+
+Then power-cycle the board.

+U-Boot for LibreTech CCs
+========================
+
+LibreTech CC is a single board computer manufactured by Libre Technology
+with the following specifications:
+
+V1:
+
+ - Amlogic S905X ARM Cortex-A53 quad-core SoC @ 1.5GHz
+ - ARM Mali 450 GPU
+ - 2GB DDR3 SDRAM
+ - 10/100 Ethernet
+ - HDMI 2.0 4K/60Hz display
+ - 40-pin GPIO header
+ - 4 x USB 2.0 Host
+ - eMMC, microSD
+ - Infrared receiver
+ - Jack for CVBS and Audio
+
+V2:
+
+ - Added SPI NOR
+ - Removed Jack
+
+Schematics are available on the manufacturer website.
+
+U-Boot compilation
+------------------
+
+.. code-block:: bash
+
+    $ export CROSS_COMPILE=aarch64-none-elf-
+    $ make libretech-cc_defconfig
+    $ make
+
+Use libretech-cc_v2_defconfig for v2.
+
+Image creation
+--------------
+
+To boot the system, u-boot must be combined with several earlier stage
+bootloaders:
+
+* bl2.bin: vendor-provided binary blob
+* bl21.bin: built from vendor u-boot source
+* bl30.bin: vendor-provided binary blob
+* bl301.bin: built from vendor u-boot source
+* bl31.bin: vendor-provided binary blob
+* acs.bin: built from vendor u-boot source
+
+These binaries and the tools required below have been collected and prebuilt
+for convenience at <https://github.com/BayLibre/u-boot/releases/>. These
+apply to both v1 and v2.
+
+Download and extract the libretech-cc release from there, and set FIPDIR to
+point to the `fip` subdirectory.
+
+.. code-block:: bash
+
+    $ export FIPDIR=/path/to/extracted/fip
+
+Alternatively, you can obtain the original vendor u-boot tree which
+contains the required blobs and sources, and build yourself.
+Note that old compilers are required for this to build. The compilers here
+are suggested by Amlogic, and they are 32-bit x86 binaries.
+
+.. code-block:: bash
+
+    $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
+    $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
+    $ tar xvfJ gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
+    $ tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
+    $ export PATH=$PWD/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux/bin:$PWD/gcc-linaro-arm-none-eabi-4.8-2013.11_linux/bin:$PATH
+    $ git clone https://github.com/BayLibre/u-boot.git -b libretech-cc amlogic-u-boot
+    $ cd amlogic-u-boot
+    $ make libretech_cc_defconfig
+    $ make
+    $ export FIPDIR=$PWD/fip
+
+Once you have the binaries available (either through the prebuilt download,
+or having built the vendor u-boot yourself), you can then proceed to glue
+everything together. Go back to mainline U-Boot source tree then :
+
+.. code-block:: bash
+
+    $ mkdir fip
+
+    $ cp $FIPDIR/gxl/bl2.bin fip/
+    $ cp $FIPDIR/gxl/acs.bin fip/
+    $ cp $FIPDIR/gxl/bl21.bin fip/
+    $ cp $FIPDIR/gxl/bl30.bin fip/
+    $ cp $FIPDIR/gxl/bl301.bin fip/
+    $ cp $FIPDIR/gxl/bl31.img fip/
+    $ cp u-boot.bin fip/bl33.bin
+
+    $ $FIPDIR/blx_fix.sh \
+    	fip/bl30.bin \
+    	fip/zero_tmp \
+    	fip/bl30_zero.bin \
+    	fip/bl301.bin \
+    	fip/bl301_zero.bin \
+    	fip/bl30_new.bin \
+    	bl30
+
+    $ $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0
+
+    $ $FIPDIR/blx_fix.sh \
+    	fip/bl2_acs.bin \
+    	fip/zero_tmp \
+    	fip/bl2_zero.bin \
+    	fip/bl21.bin \
+    	fip/bl21_zero.bin \
+    	fip/bl2_new.bin \
+    	bl2
+
+    $ $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
+    $ $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
+    $ $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin
+    $ $FIPDIR/gxl/aml_encrypt_gxl --bl2sig --input fip/bl2_new.bin --output fip/bl2.n.bin.sig

+    		--bl31 fip/bl31.img.enc \
+    		--bl33 fip/bl33.bin.enc
+
+and then write the image to SD with:
+
+.. code-block:: bash
+
+    $ DEV=/dev/your_sd_device
+    $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
+    $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
+
+Note that Amlogic provides aml_encrypt_gxl as a 32-bit x86 binary with no
+source code. Should you prefer to avoid that, there are open source reverse
+engineered versions available:
+
+1. gxlimg <https://github.com/repk/gxlimg>, which comes with a handy
+   Makefile that automates the whole process.
+2. meson-tools <https://github.com/afaerber/meson-tools>
+
+However, these community-developed alternatives are not endorsed by or
+supported by Amlogic.

+U-Boot for ODROID-C4
+====================
+
+ODROID-C4 is a single board computer manufactured by Hardkernel
+Co. Ltd with the following specifications:
+
+ - Amlogic S905X3 Arm Cortex-A55 quad-core SoC
+ - 4GB DDR4 SDRAM
+ - Gigabit Ethernet
+ - HDMI 2.1 display
+ - 40-pin GPIO header
+ - 4x USB 3.0 Host
+ - 1x USB 2.0 Host/OTG (micro)
+ - eMMC, microSD
+ - UART serial
+ - Infrared receiver
+
+Schematics are available on the manufacturer website.

+U-Boot for Amlogic SEI610
+=========================

+
+ - Amlogic S905X3 ARM Cortex-A55 quad-core SoC
+ - 2GB DDR4 SDRAM
+ - 10/100 Ethernet (Internal PHY)
+ - 1 x USB 3.0 Host
+ - 1 x USB Type-C DRD
+ - 1 x FTDI USB Serial Debug Interface
+ - eMMC
+ - SDcard
+ - Infrared receiver
+ - SDIO WiFi Module

+U-Boot for WeTek Core2
+======================
+
+WeTek Core2 is an Android STB based on the Q200 reference design with
+the following specifications:
+
+ - Amlogic S912 ARM Cortex-A53 octo-core SoC @ 1.5GHz
+ - ARM Mali T820 GPU
+ - 3GB DDR4 SDRAM
+ - 10/100 Realtek RTL8152 Ethernet (internal USB)
+ - HDMI 2.0 4K/60Hz display
+ - 2x USB 2.0 Host, 1x USB 2.0 OTG (internal)
+ - 32GB eMMC
+ - microSD
+ - SDIO Wifi Module, Bluetooth
+ - Two channel IR receiver
+
+U-Boot compilation
+------------------
+
+.. code-block:: bash
+
+    $ export CROSS_COMPILE=aarch64-none-elf-
+    $ make wetek-core2_defconfig
+    $ make
+
+Image creation
+--------------
+
+Amlogic does not provide sources for the firmware or the tools needed
+to create the bootloader image, and WeTek has not publicly shared the
+precompiled FIP binaries. However the public Khadas VIM2 sources also
+work with the Core2 box so we can use the Khadas git tree:
+
+.. code-block:: bash
+
+    $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
+    $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
