          If booting directly from flash you need to enable this option

          SPR_SR_DSX bit is status register bit indicating whether
          the last exception has happened in delay slot.
 
          OpenRISC architecture makes it optional to have it implemented
          in hardware, and Marvin and Highland SoC do not have it.
 
          Say N here if you know that your OpenRISC processor has
