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] + [AML_USE_ATOS=1 when using ATOS as BL32] + +This port has been tested on a A113D board.
