111 config OPENRISC_NO_SPR_SR_DSX
112 bool "use SPR_SR_DSX software emulation" if OR1K_1200
115 SPR_SR_DSX bit is status register bit indicating whether
116 the last exception has happened in delay slot.
118 OpenRISC architecture makes it optional to have it implemented
119 in hardware and the OR1200 does not have it.
121 Say N here if you know that your OpenRISC processor has
122 SPR_SR_DSX bit implemented. Say Y if you are unsure.
125 string "Default kernel command string"
128 On some architectures there is currently no way for the boot loader
