Add a serial driver for the SiFive UART, found on SiFive FU540 devices
(among others).
The underlying serial IP block is relatively basic, and currently does
not support serial break detection. Further information on the IP
block can be found in the documentation and Chisel sources:
https://static.dev.sifive.com/FU540-C000-v1.0.pdf
https://github.com/sifive/sifive-blocks/tree/master/src/main/scala/devices/uart
This driver was written in collaboration with Wesley Terpstra
<wesley@sifive.com>.
Tested on a SiFive HiFive Unleashed A00 board, using BBL and the open-
source FSBL (using a DT file based on what's targeted for mainline).
This revision incorporates changes based on comments by Julia Lawall
<julia.lawall@lip6.fr>, Emil Renner Berthing <kernel@esmil.dk>, and
Andreas Schwab <schwab@suse.de>. Thanks also to Andreas for testing
the driver with his userspace and reporting a bug with the
set_termios implementation.

Say Y here if you wish to have the internal AT91 UARTs

|
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.
|
|
|
|
If unsure, say N.
