7.43. Xilinx Versal NET
Trusted Firmware-A implements the EL3 firmware layer for Xilinx Versal NET. The platform only uses the runtime part of TF-A as Xilinx Versal NET 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:
`bash
make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal_net bl31
`
To build bl32 TSP you have to rebuild bl31 too
`bash
make CROSS_COMPILE=aarch64-none-elf- PLAT=versal_net SPD=tspd RESET_TO_BL31=1 bl31 bl32
`
To build TF-A for JTAG DCC console:
`bash
make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal_net VERSAL_NET_CONSOLE=dcc bl31
`
