From: Abner Chang <abner.ch...@amd.com> IpmiBmcElog is cloned from edk2-platforms/Features/Intel/OutOfBandManagement/ IpmiFeaturePkg/BmcElog in order to consolidate edk2 system manageability support in one place. Uncustify is applied to C files and no functionalities are changed in this patch.
We will still keep the one under IpmiFeaturePkg/BmcElog until the reference to this instance are removed from platforms.
