109 SPR_SR_DSX bit is status register bit indicating whether
110 the last exception has happened in delay slot.
111
112 OpenRISC architecture makes it optional to have it implemented
113 in hardware and the OR1200 does not have it.

115 Say N here if you know that your OpenRISC processor has
116 SPR_SR_DSX bit implemented. Say Y if you are unsure.
