Xilinx Zynq UltraScale+ MPSoC
|
|
=============================
|
|
|
|
Trusted Firmware-A (TF-A) implements the EL3 firmware layer for Xilinx Zynq
|
|
UltraScale + MPSoC.
|
|
The platform only uses the runtime part of TF-A as ZynqMP already has a
|
|
BootROM (BL1) and FSBL (BL2).
|
|
|
|
BL31 is TF-A.
|
|
BL32 is an optional Secure Payload.
|
|
BL33 is the non-secure world software (U-Boot, Linux etc).
|
|
|
|
To build:
|
|
|
|
.. code:: bash
|
|
|
|
make CROSS_COMPILE=aarch64-none-elf- PLAT=zynqmp bl31
|
|
|
|
To build bl32 TSP you have to rebuild bl31 too:
|
|
|
|
.. code:: bash
|
|
|
|
make CROSS_COMPILE=aarch64-none-elf- PLAT=zynqmp SPD=tspd bl31 bl32
|
|
|
|
To build TF-A for JTAG DCC console:
|
|
|
|
.. code:: bash
|
|
|
|
make CROSS_COMPILE=aarch64-none-elf- PLAT=zynqmp RESET_TO_BL31=1 bl31 ZYNQMP_CONSOLE=dcc
|
|
|
|
ZynqMP platform specific build options
|
|
--------------------------------------
|
|
|
|
- ``ZYNQMP_ATF_MEM_BASE``: Specifies the base address of the bl31 binary.
|
|
- ``ZYNQMP_ATF_MEM_SIZE``: Specifies the size of the memory region of the bl31 binary.
|
|
- ``ZYNQMP_BL32_MEM_BASE``: Specifies the base address of the bl32 binary.
|
|
- ``ZYNQMP_BL32_MEM_SIZE``: Specifies the size of the memory region of the bl32 binary.
|
|
|
|
- ``ZYNQMP_CONSOLE``: Select the console driver. Options:
|
|
|
|
- ``cadence``, ``cadence0``: Cadence UART 0
|
|
- ``cadence1`` : Cadence UART 1
|
|
|
|
FSBL->TF-A Parameter Passing
|
|
----------------------------
|
|
|
|
The FSBL populates a data structure with image information for TF-A. TF-A uses
|
|
that data to hand off to the loaded images. The address of the handoff data
|
|
structure is passed in the ``PMU_GLOBAL.GLOBAL_GEN_STORAGE6`` register. The
|
|
register is free to be used by other software once TF-A has brought up
|
|
further firmware images.
|
|
|
|
Power Domain Tree
|
|
-----------------
|
|
|
|
The following power domain tree represents the power domain model used by TF-A
|
|
for ZynqMP:

The 4 leaf power domains represent the individual A53 cores, while resources
|
|
common to the cluster are grouped in the power domain on the top.
