This keeps coming up and many of us are just carrying this patch series in downstream repos which is horrible. The problem patch in this series [1] is 'imx8mm: Fix USB reg addresses for i.MX8MM' [2] as we all want to get hard-coded base addresses out of the drivers. The proposed solution is to get the controller base addresses from PLATDATA in the SPL (and DM/DT for U-Boot). Can anyone take this part on or provide some examples of how to use platdata/of-platdata?
