If we really need this, I'm pro adding that kind of interface, sure.
However, at least for the MX51 stuff, altering the init order wasn't
necessary at all eventually, and I'm not sure about other SoCs.

I also didn't follow all patches in this area I fear - could you
summarize which SoC wants it differently than the current code does it?

Thanks,
Daniel
