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