Tobias Klauser 4d9d7d896d serial: altera_uart: add earlycon support 
Nios2 currently uses its own early printk implementation, rather than
using unified earlycon support to show boot messages on altera_uart.

Add earlycon support to altera_uart so that other archs may use it.
Also, this (together with the corresponding patch for altera_jtaguart)
will allow the early printk implementation in arch/nios2 to be removed
in a future patch.

Say Y here if you wish to have the internal AT91 / AT32 UARTs
appear as /dev/ttyATn (major 204, minor starting at 154)
instead of the normal /dev/ttySn (major 4, minor starting at
64). This is necessary if you also want other UARTs, such as
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.
Say Y if you have an external 8250/16C550 UART. If unsure, say N.
config SERIAL_KGDB_NMI
bool "Serial console over KGDB NMI debugger port"
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.

The pmac_zilog driver for the z85C30 chip on many powermacs
historically used the device numbers for /dev/ttySn. The
8250 serial port driver also uses these numbers, which means
the two drivers being unable to coexist; you could not use
both z85C30 and 8250 type ports at the same time.
If this option is not selected, the pmac_zilog driver will
use the device numbers allocated for /dev/ttyPZn. This allows
the pmac_zilog and 8250 drivers to co-exist, but may cause
existing userspace setups to break. Programs that need to
access the built-in serial ports on powermacs will need to
be reconfigured to use /dev/ttyPZn instead of /dev/ttySn.
If you enable this option, any z85c30 ports in the system will
be registered as ttyS0 onwards as in the past, and you will be

help
Support for early debug console using Spreadtrum's serial. This enables
the console before standard serial driver is probed. This is enabled
with "earlycon" on the kernel command line. The console is
enabled when early_param is processed.

This driver is for the on-chip Serial Controller on
STMicroelectronics STM32 MCUs.
USART supports Rx & Tx functionality.
It support all industry standard baud rates.
If unsure, say N.

help
This driver is for Marvell EBU SoC's UART. If you have a machine
based on the Armada-3700 SoC and wish to use the on-board serial
port,
say 'Y' here.
Otherwise, say 'N'.
config SERIAL_MVEBU_CONSOLE
bool "Console on Marvell EBU serial port"
depends on SERIAL_MVEBU_UART
select SERIAL_CORE_CONSOLE
select SERIAL_EARLYCON
default y
help
Say 'Y' here if you wish to use Armada-3700 UART as the system console.
(the system console is the device which receives all kernel messages
and warnings and which allows logins in single user mode)
Otherwise, say 'N'.
