| 2 | ================================ |
| 3 | |
| 4 | Trusted Firmware-A implements the EL3 firmware layer for Xilinx Versal. |
| 5 | The platform only uses the runtime part of TF-A as Xilinx Versal already has a |
| 6 | 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 bl31 |
| 15 | ``` |
| 16 | |
| 17 | To build ATF for different platform (for now its just versal virtual "versal_virt") |
| 18 | ```bash |
| 19 | make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal VERSAL_PLATFORM=versal_virt bl31 |
| 20 | ``` |

| 22 | # Xilinx Versal platform specific build options |
| 23 | * `VERSAL_ATF_MEM_BASE`: Specifies the base address of the bl31 binary. |
| 24 | * `VERSAL_ATF_MEM_SIZE`: Specifies the size of the memory region of the bl31 binary. |
| 25 | * `VERSAL_BL32_MEM_BASE`: Specifies the base address of the bl32 binary. |
| 26 | * `VERSAL_BL32_MEM_SIZE`: Specifies the size of the memory region of the bl32 binary. |
| 27 | |
| 28 | * `VERSAL_CONSOLE`: Select the console driver. Options: |
| 29 | - `pl011`, `pl011_0`: ARM pl011 UART 0 |
| 30 | - `pl011_1` : ARM pl011 UART 1 |
| 31 | |
| 32 | * `VERSAL_PLATFORM`: Select the platform. Options: |
| 33 | - `versal_virt` : Versal Virtual platform |
