          This alows you have support for extreamly simple bootloader

          This option controls memory controler initizalization

          When using bootloader, memory controler initialization is

          usualy done by boot the bootloader. Memory timings might not

          be ideal, so if you know the right timings it woun't hurt to

          enable it.

          If booting directly from flash you need to enable this option

          and if neccessery provide memory timings.

          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 Marvin and Highland SoC do 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.

          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.

          Say Y if you are unsure.

        help

          Write to .text or .rodata sections is most probably kernel bug.

          Enabling this will cause an oops at the instruction that tries to

          corrupt kernel.

          This has no performance implication but should help locating bugs.

          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.

config OR32_EXCEPTION_DEBUG

        bool "Print processor state at each exception"

        help

          This option will make your kernel unusable for all but kernel

          debugging.

          Say N if you are unsure.

config OR32_ESR_EXCEPTION_BUG_CHECK

        bool "Check for possible ESR exception bug"

          This option enables some checks that might expose some problems
