109 config OPENRISC_NO_SPR_SR_DSX
110 bool "use SPR_SR_DSX software emulation" if OR1K_1200
113 SPR_SR_DSX bit is status register bit indicating whether
114 the last exception has happened in delay slot.
116 OpenRISC architecture makes it optional to have it implemented
117 in hardware and the OR1200 does not have it.
119 Say N here if you know that your OpenRISC processor has
120 SPR_SR_DSX bit implemented. Say Y if you are unsure.
123 string "Default kernel command string"
126 On some architectures there is currently no way for the boot loader
127 to pass arguments to the kernel. For these architectures, you should
