The problem is that the i.MX6 shares only the name and the core. And share the core is nothing (as i.MX can share the ARM core of any other product in the world) It's like i.MX6UL was the adopted brother. It shares the name but no genetic features. Of course we can use the marketing name on OVERRIDE, but I would prefer if we focus on the SoC convergence instead. > > If we try to express SOC features via OVERRIDE mechanism, it's imho > doomed. I have a crush on philosophy, so I apologize in advance. But i.MX is basicaly it's GPU. Mainly if you think about i.MX6. Represent GPU characteristics on OVERRIDE is not represent a feature, but a core feature. However, I remember Otavio's argument i.MX6 is the exception now, not the rule.
