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 bl32 TSP you have to rebuild bl31 too
18```bash
19make CROSS_COMPILE=aarch64-none-elf- PLAT=versal_net SPD=tspd RESET_TO_BL31=1 bl31 bl32
20```
21
22To build TF-A for JTAG DCC console:
23```bash
24make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal_net VERSAL_NET_CONSOLE=dcc bl31
25```
