          If you say Y here, it will be possible to remotely debug the kernel
          using gdb. This enlarges your kernel ELF image disk size by several
          megabytes and requires a machine with more than 16 MB, better 32 MB
          RAM to avoid excessive linking time. This is only useful for kernel
          hackers. If unsure, say N.

        help
          If you say Y here, GDB stub will break into the program as soon as
          possible, leaving the program counter at the beginning of
          start_kernel() in init/main.c.

config GDB_CONSOLE
        bool "Console output to GDB"
        depends on GDBSTUB
        help
          If you are using GDB for remote debugging over a serial port and
          would like kernel messages to be formatted into GDB $O packets so
          that GDB prints them as program output, say 'Y'.
