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