   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.

  37           Include in-kernel hooks for kgdb, the Linux kernel source level
  38           debugger.  See <http://kgdb.sourceforge.net/> for more information.
  39           Unless you are intending to debug the kernel, say N here.
