Trusted Firmware-A (TF-A) implements the EL3 firmware layer for Allwinner
SoCs with ARMv8 cores. Only BL31 is used to provide proper EL3 setup and
PSCI runtime services.

U-Boot's SPL acts as a loader, loading both BL31 and BL33 (typically U-Boot).
Loading is done from SD card, eMMC or SPI flash, also via an USB debug
interface (FEL).

BL31 lives in SRAM A2, which is documented to be accessible from secure
world only.
