above patch is not suitable for 832x becuase mar register has only 26 bit (6 bit are resrved) what should be done
Simply do not define fun->upm_mar_chip_offset in your BSP code. It is used on the TQM8548 modules to driver some board-specific chip select logic. Anyhow, do you need to support a multi-chip (multi-die) device all?
