Introduce the preliminary support for the Amlogic A113D (AXG) SoC. This port is a minimal implementation of BL31 capable of booting mainline U-Boot, Linux and chainloading BL32 (ATOS). Tested on a A113D board. Signed-off-by: Carlo Caione <ccaione@baylibre.com> Change-Id: Ic4548fa2f7c48d61b485b2a6517ec36c53c20809

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]
|
|
|
|
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.
