Re: [edk2-devel] [PATCH v1 1/1] IpmiFeaturePkg/GenericIpmi: Support Standalone MM

["Chang, Abner via groups.io" <abner.chang=amd.com@groups.io>]

[AMD Official Use Only - General]

BTW Lisa,
As Issac told me the implementation which Intel upstream to IpmiFeaturePkg was from a pretty old intel code base. Also, something like FAST_VIDEO_SUPPORT, BmcSlaveAddress and GetBmcStatus seems not used. I think those code should be removed as well.
