As the of-serial driver is now 8250 specific, we can move the
file to a more appropriate place in teh 8250 subdirectory and
adapt the Kconfig help text and file name.
I'm leaving the CONFIG_SERIAL_OF_PLATFORM symbol unchanged
to avoid breaking user configuration files unnecessarily.

The NWP serial driver is no longer needed, as the two users of

Earlycon allows to have an early debugging console that doesn't need
to be statically configured in the kernel config, like earlyprintk,
but is set up through the stdout-path DT property.
This allows to have the early debugging always built into the
kernel and enabled on demand without clashing between different boards
or architectures.

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.
Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

Being a soft core, it can be located not only on PPC or Microblaze

Since the driver already does endianness detection we only need to
change the Kconfig to use it in other arches.

A configuration that enables earlycon but not the core console
code causes a link error:
drivers/built-in.o: In function `setup_earlycon':
drivers/tty/serial/earlycon.c:70: undefined reference to `uart_parse_earlycon'
That error can be triggered by the newly added samsung earlycon support,
which is missing a 'select' statement.
As suggested by Peter Hurley, solves the problem by moving the
'select SERIAL_EARLYCON' statement to the samsung console driver
option, as it is done by all other console drivers.

Two config options exist to define powerpc MPC8xx:

* CONFIG_8xx
In addition, CONFIG_PPC_8xx also defines CONFIG_CPM1 as
communication co-processor
arch/powerpc/platforms/Kconfig.cputype has contained the following
comment about CONFIG_8xx item for some years:
"# this is temp to handle compat with arch=ppc"
It looks like not many places still have that old CONFIG_8xx used,

As more ARM platforms are moving into ARCH_MULTIPLATFORM, we can now

this driver, causing a Kconfig warning:
warning: (ARCH_INTEGRATOR_AP) selects SERIAL_AMBA_PL010 which has unmet direct dependencies (TTY && HAS_IOMEM && ARM_AMBA && (BROKEN || !ARCH_VERSATILE))
It turns out that it has not been broken on versatile for a long time,

Exynos7 has a similar serial controller to that present in older Samsung
SoCs. To re-use the existing serial driver on Exynos7 we need to have
SERIAL_SAMSUNG_UARTS_4 and SERIAL_SAMSUNG_UARTS selected. This is not
possible because these symbols are dependent on PLAT_SAMSUNG which is
not present for the ARMv8 based exynos7.
Change the dependency of these symbols from PLAT_SAMSUNG to the serial
driver thus making it available on exynos7. As the existing platform
specific code making use of these symbols is related to uart driver this
change in dependency should not cause any issues.

Dedicated CTS and RTS pins are unusable together with a lot of other
peripherals because they share the same line. Pinctrl is limited.
Moreover, the AUART controller doesn't handle DTR/DSR/DCD/RI signals,
so we have to control them via GPIO.
This patch permits to use GPIOs to control the CTS/RTS/DTR/DSR/DCD/RI
signals.
