| 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. |

| 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. |
