Hi,
with SOM boards low level sdhci setting is not fully done. There are additional registers which are normally programmed via psu_init() but in this case they are not initialized. Information can be taken from DT and via firmware interface that values can be setup and that's exactly what this series is doing.
Thanks, Michal
