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
```
Xilinx Versal NET platform specific build options
-------------------------------------------------
* `VERSAL_NET_ATF_MEM_BASE`: Specifies the base address of the bl31 binary.
* `VERSAL_NET_ATF_MEM_SIZE`: Specifies the size of the memory region of the bl31 binary.
* `VERSAL_NET_BL32_MEM_BASE`: Specifies the base address of the bl32 binary.
* `VERSAL_NET_BL32_MEM_SIZE`: Specifies the size of the memory region of the bl32 binary.
* `VERSAL_NET_CONSOLE`: Select the console driver. Options:
- `pl011`, `pl011_0`: ARM pl011 UART 0 (default)
- `pl011_1` : ARM pl011 UART 1
- `dcc` : JTAG Debug Communication Channel(DCC)
* `TFA_NO_PM` : Platform Management support.
- 0 : Enable Platform Management (Default)
- 1 : Disable Platform Management
* `CPU_PWRDWN_SGI`: Select the SGI for triggering CPU power down request to
secondary cores on receiving power down callback from
firmware. Options:
- `0` : SGI 0
- `1` : SGI 1
- `2` : SGI 2
- `3` : SGI 3
- `4` : SGI 4
- `5` : SGI 5
- `6` : SGI 6 (Default)
- `7` : SGI 7
