 158           external 8250/16C550 compatible UARTs.
 159           The ttySn nodes are legally reserved for the 8250 serial driver
 160           but are often misused by other serial drivers.

 171           This special driver allows you to temporary use NMI debugger port
 172           as a normal console (assuming that the port is attached to KGDB).
 173
 174           Unlike KDB's disable_nmi command, with this driver you are always
 175           able to go back to the debugger using KGDB escape sequence ($3#33).
 176           This is because this console driver processes the input in NMI
 177           context, and thus is able to intercept the magic sequence.
 178
 179           Note that since the console interprets input and uses polling
 180           communication methods, for things like PPP you still must fully
 181           detach debugger port from the KGDB NMI (i.e. disable_nmi), and
 182           use raw console.

 840           The pmac_zilog driver for the z85C30 chip on many powermacs
