New SoC is a78 based with gicv3 and uart over pl011. Communication interfaces are similar to Versal NET platform. System starts with AMD PLM firmware which loads TF-A(bl31) to memory, which is already configured, and jumps to it. PLM also prepare handoff structure for TF-A with information what components were load and flags which indicate which EL level SW should be started.

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
|
||
```
