+config SH_STANDARD_BIOS
+ bool "Use LinuxSH standard BIOS"
+ depends on SUPERH32
+ help
+ Say Y here if your target has the gdb-sh-stub
+ package from www.m17n.org (or any conforming standard LinuxSH BIOS)
+ in FLASH or EPROM. The kernel will use standard BIOS calls during
+ boot for various housekeeping tasks (including calls to read and
+ write characters to a system console, get a MAC address from an
+ on-board Ethernet interface, and shut down the hardware). Note this
+ does not work with machines with an existing operating system in
+ mask ROM and no flash (WindowsCE machines fall in this category).
+ If unsure, say N.
+
+config STACK_DEBUG
+ bool "Check for stack overflows"
+ depends on DEBUG_KERNEL && SUPERH32
+ help
+ This option will cause messages to be printed if free stack space
+ drops below a certain limit. Saying Y here will add overhead to
+ every function call and will therefore incur a major
+ performance hit. Most users should say N.
+
+config 4KSTACKS
+ bool "Use 4Kb for kernel stacks instead of 8Kb"
+ depends on DEBUG_KERNEL && (MMU || BROKEN) && !PAGE_SIZE_64KB
+ help
+ If you say Y here the kernel will use a 4Kb stacksize for the
+ kernel stack attached to each process/thread. This facilitates
+ running more threads on a system and also reduces the pressure
+ on the VM subsystem for higher order allocations. This option
+ will also use IRQ stacks to compensate for the reduced stackspace.
+
+config IRQSTACKS
+ bool "Use separate kernel stacks when processing interrupts"
+ depends on DEBUG_KERNEL && SUPERH32 && BROKEN
+ help
+ If you say Y here the kernel will use separate kernel stacks
+ for handling hard and soft interrupts. This can help avoid
+ overflowing the process kernel stacks.
+
+config DUMP_CODE
+ bool "Show disassembly of nearby code in register dumps"
+ depends on DEBUG_KERNEL && SUPERH32
+ default y if DEBUG_BUGVERBOSE
+ default n
+ help
+ This prints out a code trace of the instructions leading up to
+ the faulting instruction as a debugging aid. As this does grow
+ the kernel in size a bit, most users will want to say N here.
+
+ Those looking for more verbose debugging output should say Y.
+
+config DWARF_UNWINDER
+ bool "Enable the DWARF unwinder for stacktraces"
+ select FRAME_POINTER
+ depends on SUPERH32
+ default n
+ help
+ Enabling this option will make stacktraces more accurate, at
+ the cost of an increase in overall kernel size.
+
+config SH_NO_BSS_INIT
+ bool "Avoid zeroing BSS (to speed-up startup on suitable platforms)"
+ depends on DEBUG_KERNEL
+ default n
+ help
+ If running in painfully slow environments, such as an RTL
+ simulation or from remote memory via SHdebug, where the memory
+ can already be guaranteed to ber zeroed on boot, say Y.
+
+ For all other cases, say N. If this option seems perplexing, or
+ you aren't sure, say N.
