Nov 2020 Intel announcement about Pluton, https://itpeernetwork.intel.com/intel-and-microsoft-plan-to-...
> Secure platforms anchor on a hardware Root of Trust as the foundation. Given Intel’s diverse ecosystem, our vision is to offer multiple Root of Trust options that ensure isolation of resources, keys and security assets. The partnership with Microsoft to offer Pluton will further broaden the choices available to our mutual customers.
Hopefully a future Intel SoC will include an optional FPGA-based RoT where customer hardware owners can load the open-source firmware of their choice.
Edit: Pluton will be included in upcoming Arm laptops with SoCs from the Qualcomm-Nuvia (former Apple M1) team.
This is sarcasm, right? It must be sarcasm.
Maybe I'm out of the loop but I would guess that hell would freeze over before Intel releases something like this, let alone an FPGA Root of Trust.
