I agree. If there are run time check required in code to treat the variants of Keystone SoC differently, then this change is needed. At this time, SoC DTS captures these differences. IMHO, If a future Keystone SoC support required SoC specific compatibility string to customize SoC specific initialization code, then it can be introduced at that time. I am not sure why this is introduced with out an example usage.
