AM5718: HS-FS AM57x Parts

Part Number: AM5718

Tool/software:

Hello,

I am working with a team that is developing on an AM57-based platform and seeking to incorporate secure boot into their product. The newer AM62 has the HS-FS parts but I cannot find a clear answer online regarding the AM57.

1) Is there an HS-FS AM57x part?

2) How do I determine this when looking at part numbers? Or have all new AM57s just switched to HS-FS?

3) If there are HS parts, how can I get access to the AM57 security documentation and tooling (keywriter and anything else)?

Thanks in advance
