108 config OPENRISC_NO_SPR_SR_DSX
109 bool "use SPR_SR_DSX software emulation" if OR1K_1200
112 SPR_SR_DSX bit is status register bit indicating whether
113 the last exception has happened in delay slot.
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.
122 string "Default kernel command string"
125 On some architectures there is currently no way for the boot loader
126 to pass arguments to the kernel. For these architectures, you should
