172 | This special driver allows you to temporary use NMI debugger port | |

174 | ||
175 | Unlike KDB's disable_nmi command, with this driver you are always | |
176 | able to go back to the debugger using KGDB escape sequence ($3#33). | |
177 | This is because this console driver processes the input in NMI | |
178 | context, and thus is able to intercept the magic sequence. | |
179 | ||
180 | Note that since the console interprets input and uses polling | |
181 | communication methods, for things like PPP you still must fully | |
182 | detach debugger port from the KGDB NMI (i.e. disable_nmi), and | |
183 | use raw console. | |

841 | The pmac_zilog driver for the z85C30 chip on many powermacs | |
842 | historically used the device numbers for /dev/ttySn. The | |
843 | 8250 serial port driver also uses these numbers, which means | |
844 | the two drivers being unable to coexist; you could not use | |
845 | both z85C30 and 8250 type ports at the same time. | |
846 | ||
847 | If this option is not selected, the pmac_zilog driver will | |
848 | use the device numbers allocated for /dev/ttyPZn. This allows | |
849 | the pmac_zilog and 8250 drivers to co-exist, but may cause | |
850 | existing userspace setups to break. Programs that need to | |
851 | access the built-in serial ports on powermacs will need to | |
852 | be reconfigured to use /dev/ttyPZn instead of /dev/ttySn. | |
853 | ||
854 | If you enable this option, any z85c30 ports in the system will | |
855 | be registered as ttyS0 onwards as in the past, and you will be | |
856 | unable to use the 8250 module for PCMCIA or other 16C550-style | |
857 | UARTs. | |

1660 | Say 'Y' here if you wish to use Armada-3700 UART as the system console. | |
1661 | (the system console is the device which receives all kernel messages | |
1662 | and warnings and which allows logins in single user mode) | |
1663 | Otherwise, say 'N'. | |
