This seems like a bad design to require the ipmi interface type at such
a high level in the code tree. UEFI provides plenty protocol and
library abstractions for IPMI so I would really prefer not to leak this
type of information into a PCD defined in MdePkg. Happy to discuss IPMI
support and I would really like to see edk2,
edk2-platforms/Features/ManageabilityPkg at master ·
tianocore/edk2-platforms (github.com)
<https://github.com/tianocore/edk2-platforms/tree/master/Features/ManageabilityPkg>,
microsoft/mu_feature_ipmi: Project Mu - Feature Repo- Firmware support
for IPMI (github.com) <https://github.com/microsoft/mu_feature_ipmi>,
and commercial vendors find some sort of alignment going forward as no
one wins with the mess that is in the industry now.
Thanks
Sean
