+U-Boot for BananaPi M2S (A311D & S922X)
+=======================================
+
+BananaPi BPI-M2S ships is a Single Board Computer manufactured by Sinovoip that ships in
+two variants with Amlogic S922X or A311D SoC and the following common specification:
+
+- 16GB eMMC
+- HDMI 2.1a video
+- 2x 10/100/1000 Base-T Ethernet (1x RTL8211F, 1x RTL811H)
+- 2x USB 2.0 ports
+- 2x Status LED's (green/blue)
+- 1x Power/Reset button
+- 1x micro SD card slot
+- 40-pin GPIO header
+- PWM fan header
+- UART header
+
+The S992X variant has:
+- 2GB LPDDR4 RAM
+
+The A311D variant has:
+
+- 4GB LPDDR4 RAM
+- NPU (5.0 TOPS)
+- MIPI DSI header
+- MIPI CSI header
+
+An optional RTL8822CS SDIO WiFi/BT mezzanine is available for both board variants.
+
+Schematics are available from the manufacturer: https://wiki.banana-pi.org/Banana_Pi_BPI-M2S
+
+U-Boot Compilation
+------------------
+
+.. code-block:: bash
+
+    $ export CROSS_COMPILE=aarch64-none-elf-
+    $ make bananapi-m2s_defconfig
+    $ make
+
+U-Boot Signing with Pre-Built FIP repo
+--------------------------------------
+
+.. code-block:: bash
+    $ git clone https://github.com/LibreELEC/amlogic-boot-fip --depth=1
+    $ cd amlogic-boot-fip
+    $ mkdir my-output-dir
+    $ ./build-fip.sh bananapi-m2s /path/to/u-boot/u-boot.bin my-output-dir
+
+U-Boot Manual Signing
+---------------------
+
+Amlogic does not provide sources for the firmware and tools needed to create a bootloader
+image so it is necessary to obtain binaries from sources published by the board vendor:
+
+.. 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
+
+    $ DIR=bananapi-m2s
+    $ git clone --depth 1 https://github.com/Dangku/amlogic-u-boot.git -b khadas-g12b-v2015.01-m2s $DIR
+
+    $ cd $DIR
+    $ make bananapi_m2s_defconfig
+    $ make
+    $ export UBDIR=$PWD
+
+Go back to the mainline U-Boot source tree then:
+
+.. code-block:: bash
+
+    $ mkdir fip
+
+    $ wget https://github.com/BayLibre/u-boot/releases/download/v2017.11-libretech-cc/blx_fix_g12a.sh -O fip/blx_fix.sh
