Enable serial driver to be built as a module. To do so, init the console
support on driver/module load instead of using console_initcall().
Inspired by commit 87a0b9f98a ("tty: serial: meson: enable console as
module").

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.

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.
