I haven't thought in detail about the exact fix for this, but it shouldn't be difficult. For example, it could be as simple as creating some more per-family hwmod lists of optional hwmods. Then, during init, register them based on the feature flag. Longer term, it may be that we handle this using DT, but I'm not sure we will use DT to describe that level of SoC detail. > Currently hwmod is also dependent on cpu_is_xxxx to register respective modules.

Correct for today, but not difficult to remedy by fixing up the hwmod init.
