Eh, I wanted to ask to not put it inside arm/, but judging by your usage
- you did not create drivers for both of these (WED and PCIe mirror).

You only need them to expose address spaces via syscon.

This actually looks hacky. Either WED and PCIe mirror are part of
network driver, then add the address spaces via "reg". If they are not,
but instead they are separate blocks, why you don't have drivers for them?


Best regards,
