 157           instead of the normal /dev/ttySn (major 4, minor starting at

 159           external 8250/16C550 compatible UARTs.
 160           The ttySn nodes are legally reserved for the 8250 serial driver

 172           This special driver allows you to temporary use NMI debugger port
 173           as a normal console (assuming that the port is attached to KGDB).
 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.

 843           The pmac_zilog driver for the z85C30 chip on many powermacs
