1Xilinx Versal NET 2================= 3 4Trusted Firmware-A implements the EL3 firmware layer for Xilinx Versal NET. 5The platform only uses the runtime part of TF-A as Xilinx Versal NET already 6has a BootROM (BL1) and PMC FW (BL2). 7 8BL31 is TF-A. 9BL32 is an optional Secure Payload. 10BL33 is the non-secure world software (U-Boot, Linux etc). 11 12To build: 13```bash 14make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal_net bl31 15``` 16 17To build TF-A for JTAG DCC console: 18```bash 19make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal_net VERSAL_NET_CONSOLE=dcc bl31 20``` 21 22Xilinx Versal NET platform specific build options 23------------------------------------------------- 24 25* `VERSAL_NET_ATF_MEM_BASE`: Specifies the base address of the bl31 binary. 26* `VERSAL_NET_ATF_MEM_SIZE`: Specifies the size of the memory region of the bl31 binary. 27* `VERSAL_NET_BL32_MEM_BASE`: Specifies the base address of the bl32 binary. 28* `VERSAL_NET_BL32_MEM_SIZE`: Specifies the size of the memory region of the bl32 binary. 29 30* `VERSAL_NET_CONSOLE`: Select the console driver.
