- 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)
- Code Locations
- ~~~~~~~~~~~~~~
- - Trusted Firmware-A:
- `link <https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/>`__
- 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.
