Thanks, I'll check it out.

Do read and understand the License this project operates under https://trustedfirmware-a.readthedocs.io/en/latest/license.html and your responsibilities if you submit code.
Hope this helps.

(i.e., RK3566 )
Hello, Everyone,
If I want to add a new platform support in TF-A for RK3566 as an example, what Documentation do I need to read.
Using RK3399 as a contrast ( because most of RK3399 doc is opened in internet ), we already know this SoC is supported in OPTEE and TF-A. And I can get RK3399 Docs:* TRM V1.3 Part 1*, T*RM V1.3 Part2*, *TRM V1.4 Part 1*, *Datasheet V2.1*. I can see in *TRM chapter 16 System Security, *there are some descriptions about system security, and references to other system registers, like *SGRF, *etc, but it still seems to me insufficiently ( No SGRF description ) to finish a full support platform implementation in TF-A. Some people said I need to sign an NDA with Rockchip to get Security related part docs. But when I reach to Rockchip, they said all docs are opened already, No NDA options. When I talked to one partner/distributor of Rockchip, only security related doc is also some doc I can find on internet.
So I am curious and confused, can I, as a third party developer, develop a new platform implementation for TF-A / OPTEE ( specially for Rockchip Platform )?
Thanks
