| Amlogic Meson S905 (GXBB) |
| ========================= |
| |
| The Amlogic Meson S905 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=gxbb bl31 |
| |
| This port has been tested in a ODROID-C2. After building it, follow the |
| instructions in the `U-Boot repository`_, replacing the mentioned **bl31.bin** |
| by the one built from this port. |
