          This alows you have support for extreamly simple bootloader
          in the kernel. It will just copy kernel image from FLASH to RAM and
          start executing it.

        help
          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.

        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.

          Say Y if you are unsure. 

config OR32_GUARD_PROTECTED_CORE
        bool "Write protect read only part of kernel"
        default y
        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"
        default n
        help
          This option will make your kernel unusable for all but kernel
          debugging.

          Say N if you are unsure.

          a bus system, i.e. the way the CPU talks to the other stuff inside
          your box.  If you say Y here, the kernel will include drivers and
          infrastructure code to support PCI bus devices.
