gxbb: Initial port of 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:
- Partial SCPI support.
- Basic PSCI support (CPU_ON, SYSTEM_RESET, SYSTEM_OFF).
- GICv2 driver set up.
- Basic SIP services (read efuse data, enable/disable JTAG).
This port has been tested in an ODROID-C2.
