+	  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

+	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.
