On receiving CPU power down callback, TF-A raises SGI interrupt to all active cores to power down each active cores. Add handler for this SGI IRQ. By default TF-A uses SGI 6 for CPU power down request. This can be configurable through CPU_PWRDWN_SGI build flag. e.g., If user wants to use SGI 7 instead of SGI 6 then provide build flag CPU_PWRDWN_SGI=7 Signed-off-by: Jay Buddhabhatti <jay.buddhabhatti@amd.com> Change-Id: Id0df32187d1de3f0af4486eb4d4930cb3ab01dbd

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 (supported are "silicon"(default) and "versal_virt")
|
|
```bash
|
|
make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal VERSAL_PLATFORM=versal_virt bl31
|
|
```
|
|
|
|
To build bl32 TSP you have to rebuild bl31 too
|
|
```bash
|
|
make CROSS_COMPILE=aarch64-none-elf- PLAT=versal 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 bl31 VERSAL_CONSOLE=dcc
|
|
```
|
|
|
|
To build TF-A with Errata management interface
|
|
```bash
|
|
make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal bl31 ERRATA_ABI_SUPPORT=1
|
|
```
|
|
|
|
To build TF-A with Straight-Line Speculation(SLS)
|
|
```bash
|
|
make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal bl31 HARDEN_SLS_ALL=1
|
|
```

Xilinx Versal platform specific build options
|
|
---------------------------------------------
|
|
|

|
|
- `pl011_1` : ARM pl011 UART 1
|
|

|
|
|
|
* `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
|
|

# PLM->TF-A Parameter Passing
|
|
------------------------------
|
|
The PLM populates a data structure with image information for the TF-A. The TF-A
|
|
uses that data to hand off to the loaded images. The address of the handoff
|
|
data structure is passed in the ```PMC_GLOBAL_GLOB_GEN_STORAGE4``` register.
|
|
The register is free to be used by other software once the TF-A is bringing up
|
|
further firmware images.
