If the SoC is sold to another company, then case1: The original SoC family is renamed to another family. case2: Based on the original SoC, a newer SoC family comes out. I'm not sure it's still fine to put the new or renamed SoCs' files into the original SoC directory. Another issue is: who will be the maintainer of new or renamed SoC family?
