112 SPR_SR_DSX bit is status register bit indicating whether
113 the last exception has happened in delay slot.
114
115 OpenRISC architecture makes it optional to have it implemented
116 in hardware and the OR1200 does not have it.

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