RTS is an output. Either flow control is used and you care about the state or
it is not used and you don't care. So setting it to active does no harm in
either case. This is inline with what Linux does.

this will allow to have no console support
Use full for bootstrap as we can save 6.5 KiB (barebox.bin) and
3.8 KiB (zbarebox.bin lzo) on at91sam9263 as example vs console simple
As on bootstrap we have often very limited size.

This patch provides a global cleanup barebox Kconfig files. This includes
replacing spaces to tabs, formatting in accordance format, removing
extraneous lines and spaces. No functional changes.

Instead of taking the value from somewhere, use the selected architecture to
select one. This ensures the selected clock source corresponds to the values
setup in the clocks-*.c from the mach directory.

The '__maybe_unused' attribute prevents the compiler from warning about an
unused variable and the 'static' will remove it entirely if it's not used.
This patch is only cosmetic.

The name "serial_ns16550" is not handy because the devices
will have the names like "serial_ns165500", "serial_ns165501",
"serial_ns165502" etc.
The names like "ns16550_serial0" and "ns16550_serial1" look
much better.
Also it is reasonable to make serial driver's names unification.
E.g. see the names for drivers in drivers/serial directory:
"netx_serial",
"mpc5xxx_serial",
"altera_serial",
"s3c_serial",
"imx_serial",
"pxa_serial",
"blackfin_serial",
"stm_serial",
"pl010_serial",
and even "g_serial" in ./drivers/usb/gadget/serial.c

Ok, I assume this should go into separate series. It fits both S5PV210 and S3C6410.
This adds support for S3C and S5P architectures (all of my knowledge) to the
serial driver. Since the only difference between them is in clock handling,
this is moved to an arch-dependent separate function.
Most modern architectures should define S3C_UART_HAS_UBRDIVSLOT and S3C_UART_HAS_UINTM.
This adds support for most

The netX internal UART latches register settings and internally uses
them only if written in the correct order. Other orders may work, but
sometimes the UART gets stuck, as the baudrate has not correctly been
set.
