  5config SH_STANDARD_BIOS
  6	bool "Use LinuxSH standard BIOS"
  7	help
  8	  Say Y here if your target has the gdb-sh-stub
  9	  package from www.m17n.org (or any conforming standard LinuxSH BIOS)
 10	  in FLASH or EPROM.  The kernel will use standard BIOS calls during
 11	  boot for various housekeeping tasks (including calls to read and
 12	  write characters to a system console, get a MAC address from an
 13	  on-board Ethernet interface, and shut down the hardware).  Note this
 14	  does not work with machines with an existing operating system in
 15	  mask ROM and no flash (WindowsCE machines fall in this category).
 16	  If unsure, say N.

 25	help
 26	  Say Y here to redirect kernel printk messages to the serial port
 27	  used by the SH-IPL bootloader, starting very early in the boot
 28	  process and ending when the kernel's serial console is initialised.
 29	  This option is only useful porting the kernel to a new machine,
 30	  when the kernel may crash or hang before the serial console is
 31	  initialised. If unsure, say N.

 33config KGDB
 34	bool "Include KGDB kernel debugger"
 35	help
 36	  Include in-kernel hooks for kgdb, the Linux kernel source level
 37	  debugger.  See <http://kgdb.sourceforge.net/> for more information.
 38	  Unless you are intending to debug the kernel, say N here.

119	  If you say Y here the resulting kernel image will be slightly larger
120	  and slower, but it will give very useful debugging information.
121	  If you don't debug the kernel, you can say N, but we may not be able
122	  to solve problems without frame pointers.
