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.

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.
