- 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.
