Subject: [edk2-platforms][PATCH 1/2] ManageabilityPkg/IpmiBmcElog: IPMI BMC Elog Driver
From: Abner Chang <abner.chang at 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.
