Functionally, I tested these patches on an RZ/A1H RSK board (after modifying the DT for the RSK vs the GENMAI board). The following worked fine: * SCIF * I2C * SDHI * Ethernet (The trick is you have to know what pins need to be set as bi-directional) I will look over the code and provide feedback separately.
