  To: devel; +Cc: Ard Biesheuvel, Leif Lindholm, Sami Mujawar, Sahil

NT_FW_CONFIG DTB contains platform information passed by
Tf-A boot stage.
This information is used for Virtual memory map generation
during PEI phase and passed on to DXE phase as a HOB, where
it is used in ConfigurationManagerDxe.
