| 2 | ================= |
| 3 | |
| 4 | Trusted Firmware-A implements the EL3 firmware layer for Xilinx Versal NET. |
| 5 | The platform only uses the runtime part of TF-A as Xilinx Versal NET already |
| 6 | has a BootROM (BL1) and PMC FW (BL2). |
| 7 | |
| 8 | BL31 is TF-A. |
| 9 | BL32 is an optional Secure Payload. |
| 10 | BL33 is the non-secure world software (U-Boot, Linux etc). |
| 11 | |
| 12 | To build: |
| 13 | ```bash |
| 14 | make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal_net bl31 |
| 15 | ``` |
