Hello Jason,

Thank you very much for the reply, please see inline.

I have seen the Intel VROC slides [0], and they mention some
facilities for integration with BMCs. I assumed they're generic for
all the hardware handled by VROC (including SATA as RSTe was
apparently made part of VROC) but now that I re-read it, I see "NVMe
RAID BMC OOB management via OS, UEFI OOB management coming with Intel
VROC 8.0" is apparently NVMe-specific.

So even if this is not useful for Tioga Pass it would still be nice to
support this feature from OpenBMC side for the next generation
servers, and we plan to work on that.

Due to the horrible actions of Russia we are no longer permitted to
talk to the Intel support representatives. So we have to count on open
documentation and communication, and we are willing to share
everything useful with the OpenBMC upstream.
