The Raspberry Pi 5 is a single-board computer based on BCM2712 that contains four Arm Cortex-A76 cores. This change introduces minimal BL31 support with PSCI that has been validated to boot Linux and a private EDK2 build. It's a drop-in replacement for the custom TF-A armstub now included in the EEPROM images.
