Broadcom Stingray
|
|
=================
|
|
|
|
Description
|
|
-----------
|
|
Broadcom's Stingray(BCM958742t) is a multi-core processor with 8 Cortex-A72 cores.
|
|
Trusted Firmware-A (TF-A) is used to implement secure world firmware, supporting
|
|
BL2 and BL31 for Broadcom Stingray SoCs.
|
|
|
|
On Poweron, Boot ROM will load bl2 image and Bl2 will initialize the hardware,
|
|
then loads bl31 and bl33 into DDR and boots to bl33.
|
|
|
|
Boot Sequence
|
|
-------------
|
|
|
|
Bootrom --> TF-A BL2 --> TF-A BL31 --> BL33(u-boot)

How to build
|
|
------------
|
|
|
|
Build Procedure
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- Prepare AARCH64 toolchain.
|
|
|
|
- Build u-boot first, and get the binary image: u-boot.bin,
|
|
|
|
- Build TF-A
|
|
|
|
Build fip:
|
|
|
|
.. code:: shell
|
|
|
|
make CROSS_COMPILE=aarch64-linux-gnu- PLAT=stingray BOARD_CFG=bcm958742t all fip BL33=u-boot.bin
|
|
|
|
Deploy TF-A Images
|
|
~~~~~~~~~~~~~~~~~~
|
|
The u-boot will be upstreamed soon, this doc will be updated once they are ready, and the link will be posted.
