1. Rename following library instances according to MDE Library Spec:
1) SerialPortLibNull => BaseSerialPortLibNull 2) DxeMemoryLib => UefiMemoryLib 3) DxeMemoryAllocationLib => UefiMemoryAllocationLib 4) CpuLib => BaseCpuLib 5) HiiLib => UefiHiiLib 6) IfrSupportLib => UefiIfrSupportLib 7) PeiPalCallLib => PeiPalLib 2. Add library instances to MDE package 1) DxePalLib 2) FvbServiceLib 3) GraphicsLib git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@6221 6f19259b-4bc3-4df7-8a09-765794883524
