| 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-none-elf- 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. |
