Subject: [edk2-platforms][PATCH 1/2] ManageabilityPkg/IpmiFrb: IPMI FRB Driver
From: Abner Chang <abner.ch...@amd.com>
IpmiFrb is cloned from
edk2-platforms/Features/Intel/OutOfBandManagement/
IpmiFeaturePkg/Frb 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/Frb until the reference to this
instance are removed from platforms.
