Re: [PATCH] MdePkg/Include: Add IPMI KCS definitions

["Chang, Abner" <abner.chang@amd.com>]

[AMD Official Use Only - General]

Ok, that would be the patch set for edk2-platform I am going to send later,  will update these two edk2 industry standard definition patches (KCS and MCTP) after edk2-platforms one.

Thanks
Abner
