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?

Best Regards,

Tim
