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
```
AMD Versal Gen 2 platform specific build options
-------------------------------------------------
* `MEM_BASE`: Specifies the base address of the bl31 binary.
* `MEM_SIZE`: Specifies the size of the memory region of the bl31 binary.
* `BL32_MEM_BASE`: Specifies the base address of the bl32 binary.
* `BL32_MEM_SIZE`: Specifies the size of the memory region of the bl32 binary.
* `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)
