+Amlogic Meson A113D (AXG)
+===========================
+
+The Amlogic Meson A113D is a SoC with a quad core Arm Cortex-A53 running at
+~1.2GHz. It also contains a Cortex-M3 used as SCP.
+
+This port is a minimal implementation of BL31 capable of booting mainline U-Boot
+and Linux:
+
+- SCPI support.
+- Basic PSCI support (CPU_ON, CPU_OFF, SYSTEM_RESET, SYSTEM_OFF). Note that CPU0
+ can't be turned off, so there is a workaround to hide this from the caller.
+- GICv2 driver set up.
+- Basic SIP services (read efuse data, enable/disable JTAG).
+
+In order to build it:
+
+.. code:: shell
+
+ CROSS_COMPILE=aarch64-none-elf- make DEBUG=1 PLAT=axg [SPD=opteed]
+ [AML_USE_ATOS=1 when using ATOS as BL32]
+
+This port has been tested on a A113D board. After building it, follow the
+instructions in the `U-Boot repository`_, replacing the mentioned **bl31.img**
+by the one built from this port.
+
+.. _U-Boot repository: https://github.com/u-boot/u-boot/blob/master/board/amlogic/s400/README
