SOCAMM is a Memory Module. SPD5118, as it's Kconfig mentions, is a sensor found within such memory modules. I didn't quite get why would you state that the SOCAMM present in Vera architecture (or CPU) does not have SPD5118 in it.
Pasting the below from the Vera Rubin product page [1] - "NVIDIA Vera CPUs add enhanced serviceability with small-outline compression-attached memory modules (SOCAMM) LPDDR5X and in-system tests for the CPU cores."

I found little details on what we should be adding in the defconfig. It would help if you could share some guidance. Do you mean to say that the defconfig should include only the configs which are necessary in development platforms and not in end-products?
