Where are the DTSes? Where are the > differences? If we keep documenting every SKU which is the same from > user/OS perspective, this list would grow crazy. Most of the differences will be user-noticeable, even if they can be runtime detected. Besides the mentioned differences in DRAM size, things like the number of CPUs, GPU compute units or video encoders/decoders can vary depending on the SKU. While the OS should certainly be able to abstract all of that away as best as possible, on user may still end up with SKU 3 and another with SKU 5 and it's important for people to know what they have. So I think we have to find a way to both keep things simple from a DTS point of view (as I said, we should be able to make do with one DTS file for the Jetson Orin NX and one for the Jetson Orin Nano with UEFI taking care of fixing up the DTS per SKU), and not lying to users. If users get a SKU 3, then that's what we should report instead of 3 (or whatever ends up being the SKU that we use in the DTS). So I want to be as complete as possible in documenting these so that when people go look for the part numbers, they can at least find some reference to them.
