[AMD Official Use Only - General] Hi Maintainers @michael.d.kinney@intel.com, @Liming Gao and @Zhiguang Liu, Please review and merge it if there is no problems with this patch, this helps the follow up development works. Please note that Isaac has his Acked-by: Isaac Oram <isaac.w.oram@intel.com> to this patch. One question, Can we assign maintainers to the files under MdePkg? Just like we have now for MdeModulePkg. For example, F: MdePkg/Include/IndustryStandard/*IpMI* F: MdePkg/Include/IndustryStandard/*Mctp* I don't see any use case like this for MdePkg.
