Trusted Firmware-A implements the EL3 firmware layer for Xilinx Versal. The platform only uses the runtime part of TF-A as Xilinx Versal already has a BootROM (BL1) and PMC FW (BL2).
BL31 is TF-A. BL32 is an optional Secure Payload. BL33 is the non-secure world software (U-Boot, Linux etc).
To build:
make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal bl31
To build ATF for different platform (for now its just versal virtual "versal_virt")
make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal VERSAL_PLATFORM=versal_virt bl31
