Xilinx Versal
|
||
|
|
=============
|
||
|
|
|
||
|
|
Trusted Firmware-A implements the EL3 firmware layer for Xilinx Versal.
|
||
|
|
The platform only uses the runtime part of TF-A as Xilinx Versal 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 bl31
|
||
|
|
```
|
||
|
|
|
||
|
|
To build ATF for different platform (for now its just versal virtual "versal_virt")
|
||
|
|
```bash
|
||
|
|
make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal VERSAL_PLATFORM=versal_virt bl31
|
||
|
|
```
|
||
|
|
|
||
|
|
