OpenRISC architecture makes it optional to have it implemented in hardware and the OR1200 does not have it. Say N here if you know that your OpenRISC processor has SPR_SR_DSX bit implemented. Say Y if you are unsure. config CMDLINE string "Default kernel command string" default "" help On some architectures there is currently no way for the boot loader to pass arguments to the kernel. For these architectures, you should supply some command-line options at build time by entering them here. menu "Debugging options" config DEBUG_STACKOVERFLOW bool "Check for kernel stack overflow" default y help Make extra checks for space avaliable on stack in some critical functions. This will cause kernel to run a bit slower, but will catch most of kernel stack overruns and exit gracefuly.
