default y
help
SPR_SR_DSX bit is status register bit indicating whether
the last exception has happened in delay slot.
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.

config DEBUG_STACKOVERFLOW
bool "Check for kernel stack overflow"
default y
help
Make extra checks for space available 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 gracefully.
Say Y if you are unsure.
config JUMP_UPON_UNHANDLED_EXCEPTION
bool "Try to die gracefully"
default y
help
Now this puts kernel into infinite loop after first oops. Till
your kernel crashes this doesn't have any influence.
Say Y if you are unsure.
config OPENRISC_ESR_EXCEPTION_BUG_CHECK
bool "Check for possible ESR exception bug"
default n
help
This option enables some checks that might expose some problems
in kernel.
Say N if you are unsure.
