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

4The Amlogic Meson S905x 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:

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 on a Lepotato. After building it, follow the
23instructions in the `gxlimg repository` or `U-Boot repository`_, replacing the
24mentioned **bl31.img** by the one built from this port.
