When compile-testing an allmodconfig kernel for a platform without
sh-sci serial ports, the SERIAL_SH_SCI_NR_UARTS symbol of type "int"
doesn't get assigned a numerical default value, but an empty string,
leading to a build failure:
.config:3814:warning: symbol value '' invalid for SERIAL_SH_SCI_NR_UARTS
...
make[3]: *** [silentoldconfig] Error 1
Fix this by explicitly providing a default value of 2, like before.

The ttySn nodes are legally reserved for the 8250 serial driver

To use this, you should create suitable ttyATn device nodes in

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.

|
This driver supports the Comtrol RocketPort EXPRESS and
|
|
RocketPort INFINITY families of PCI/PCIe multiport serial adapters.
|
|
These adapters use a "RocketPort 2" ASIC that is not compatible
|
|
with the original RocketPort driver (CONFIG_ROCKETPORT).
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called rp2.
|

|
|
If you want to compile this driver into the kernel, say Y here. If
|
|
you don't have a suitable RocketPort card installed, say N.
