+Amlogic Meson S905X2 (G12A)
+===========================
+
+The Amlogic Meson S905X2 is a SoC with a quad core Arm Cortex-A53 running at
+~1.8GHz. 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-linux-gnu- make DEBUG=1 PLAT=g12a
+
+This port has been tested on a SEI510 board. After building it, follow the
+instructions in the `gxlimg repository`_ or `U-Boot repository`_, replacing the
+mentioned **bl31.img** by the one built from this port.
