I think a .dsc.inc file was created for Platform/ARM/JunoPkg/ArmJuno.dsc
because the Juno can either build the ACPI tables with the
DynamicTablesPkg or get them statically.
Since the N1Sdp doesn't have static ACPI tables, is it necessary to have
this .dsc.inc file ? We could just add the ConfigurationManagerDxe.inf
component in the N1Sdp.dsc .

Can you add the [in] in the parameter definition ?
