2================================================

4The Amlogic Meson S905 is a SoC with a quad core Arm Cortex-A53 running at
51.5Ghz. It also contains a Cortex-M3 used as SCP.

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).

22This port has been tested in a ODROID-C2. After building it, follow the
23instructions in the `U-Boot repository`_, replacing the mentioned **bl31.bin**
24by the one built from this port.
