1Amlogic Meson A113D (AXG) 2=========================== 3 4The Amlogic Meson A113D is a SoC with a quad core Arm Cortex-A53 running at 5~1.2GHz. It also contains a Cortex-M3 used as SCP. 6 7This port is a minimal implementation of BL31 capable of booting mainline U-Boot 8and Linux: 9 10- SCPI support. 11- Basic PSCI support (CPU_ON, CPU_OFF, SYSTEM_RESET, SYSTEM_OFF). Note that CPU0 12 can't be turned off, so there is a workaround to hide this from the caller. 13- GICv2 driver set up. 14- Basic SIP services (read efuse data, enable/disable JTAG). 15 16In order to build it: 17 18.. code:: shell 19 20 CROSS_COMPILE=aarch64-none-elf- make DEBUG=1 PLAT=axg [SPD=opteed] 21 [AML_USE_ATOS=1 when using ATOS as BL32] 22 23This port has been tested on a A113D board. After building it, follow the 24instructions in the `U-Boot repository`_, replacing the mentioned **bl31.img** 25by the one built from this port. 26 27.. _U-Boot repository: https://github.com/u-boot/u-boot/blob/master/doc/board/amlogic/s400.rst 28
