Amlogic Meson S905x (GXL)
=========================
The Amlogic Meson S905x is a SoC with a quad core Arm Cortex-A53 running at
1.5Ghz. 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=gxl
This port has been tested on a Lepotato. 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.
