I am trying to keep Silicon (SOC) specific dsc file in Silicon/NXP/<Chassis Name>/<Silicon Name>
This silicon can be used in multiple Boards (Platforms).
All these Platforms are present in Platform/NXP/<Platform Name>
fd/fv binaries would be created for each platform.
The chassis dsc file has description of components/PCDs that are specific to chassis to which the silicon belongs. It would be same for all silicons that belong to same chassis.
The Silicon dsc file has description of components/PCDs that are specific to silicon and would be same for all platforms that use this silicon. It would include chassis dsc file
The Platform dsc file would include the silicon dsc file.
