Say Y here if you wish to have the internal AT91 UARTs |

appear as /dev/ttyATn (major 204, minor starting at 154) |

instead of the normal /dev/ttySn (major 4, minor starting at |
|
64). This is necessary if you also want other UARTs, such as |
|
external 8250/16C550 compatible UARTs. |
|
The ttySn nodes are legally reserved for the 8250 serial driver |
|
but are often misused by other serial drivers. |
|
|
|
To use this, you should create suitable ttyATn device nodes in |
|
/dev/, and pass "console=ttyATn" to the kernel. |

config SERIAL_KGDB_NMI |

bool "Serial console over KGDB NMI debugger port" |

depends on KGDB_SERIAL_CONSOLE |
|
help |
|
This special driver allows you to temporary use NMI debugger port |
|
as a normal console (assuming that the port is attached to KGDB). |
|
|
|
Unlike KDB's disable_nmi command, with this driver you are always |
|
able to go back to the debugger using KGDB escape sequence ($3#33). |
|
This is because this console driver processes the input in NMI |
|
context, and thus is able to intercept the magic sequence. |
|
|
|
Note that since the console interprets input and uses polling |
|
communication methods, for things like PPP you still must fully |
|
detach debugger port from the KGDB NMI (i.e. disable_nmi), and |
|
use raw console. |

If unsure, say N. |

existing userspace setups to break. Programs that need to |
