7.2. AMD Versal Gen 2
Trusted Firmware-A implements the EL3 firmware layer for AMD Versal Gen 2. The platform only uses the runtime part of TF-A as AMD Versal Gen 2 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=versal2 bl31
`
To build TF-A for JTAG DCC console:
`bash
make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal2 CONSOLE=dcc bl31
`
To build TF-A with Errata management interface
`bash
make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal2 bl31 ERRATA_ABI_SUPPORT=1
`
To build TF-A with IPI CRC check:
`bash
make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal2 bl31 IPI_CRC_CHECK=1
`
