SPDM Daemon status & Collaboration

[Zhichuang Sun]

Hi Ratan and Manoj,

The current spdmd design has multiple transport support in consideration.
It’s pretty straightforward to add a new transport support.

I have asked Patrick about the process to create a spdmd repo within
OpenBMC. I’m happy to work with you folks together to upstream our spdmd
with builtin support for multiple transport layers.

Thanks,
Zhichuang
