[AMD Official Use Only - General]
Hi Lisa,
Issac was no longer the maintainer of IpmiFeaturePkg as he was retired. Nate
had sent the maintainers update for review.
As the conversation I had with Issac, we all agreed IpmiFeaturePkg should be
deprecated as the IPMI related drivers are now located under ManageabilityPkg
in edk2-platforms. The IPMI implementation in these two packages are diverging
now, which is not good.
Could you please send this patch against ManageabilityPkg? I can help to review
it, so does Nate as he also proposed himself as the maintainers of
ManageabilityPkg.
Thanks
Abner
