[edk2-devel] [PATCH V2 14/32] AMD/VanGoghBoard: Check in SmbiosLib

["Zhai, MingXin (Duke) via groups.io" <duke.zhai=amd.com@groups.io>]

From: Duke Zhai <Duke.Zhai@amd.com>

BZ #:4640
In V2: Improve coding style.
  1.Remove the leading underscore and use double underscore at trailing in C header files.
  2.Remove old tianocore licenses and redundant license description.
  3.Improve coding style. For example: remove space between @param.

In V1:
  Provides library functions for common SMBIOS operations. Only available to DXE
  and UEFI module types.
