stm32x7.c driver is dedicated for STM32F7.
In kernel, "st,stm32-usart" and "st,stm32-uart" compatible
strings are dedicated for STM32F4.
To keep U-boot and kernel aligned, replace the serial compatible
string from "st,stm32-usart", "st,stm32-uart" to
"st,stm32f7-usart", "st,stm32f7-uart" specific for STM32F7.

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live

It is good practice to include common.h as the first header. This ensures
that required features like the DECLARE_GLOBAL_DATA_PTR macro,
configuration options and common types are available.
Fix up some files which currently don't do this. This is necessary because
driver model will soon start using global data and configuration in the
dm/read.h header file, included via dm.h. The gd->fdt_blob value will be
used to access the device tree and CONFIG options will be used to
determine whether to support inline functions in the header file.

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.
In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree only
All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.
Note this involves changing some dead code - the imx_lpi2c.c file.

On my x86 platform I've noticed, that calling dm_uninit() or the new
function dm_remove_devices_flags() does not remove the desired device at
all. Debugging showed, that the serial uclass returns -EPERM in
serial_pre_remove(). This patch sets the force parameter when calling
stdio_deregister_dev() resulting in a removal of the device.

In the two cases in the code where we use CONFIG_OMAP as a useful test
currently we can make use of CONFIG_ARCH_OMAP2PLUS instead. With that
changed we can drop all defines of CONFIG_OMAP. While in here,
CONFIG_OMAP3430 is only defined and then never used, so drop.

Add a specific serial driver for Intel MID platforms.
It has special fractional divider which can be programmed via UART_PS,
UART_MUL, and UART_DIV registers.
The UART clock is calculated as
UART clock = XTAL * UART_MUL / UART_DIV
The baudrate is calculated as
baud rate = UART clock / UART_PS / DLAB
Initialize fractional divider correctly for Intel Edison platform.
For backward compatibility we have to set initial DLAB value to 16
and speed to 115200 baud, where initial frequency is 29491200Hz, and
XTAL frequency is 38.4MHz.

commit: 65f83802b7a5b "serial: 16550: Add getfcr accessor"
breaks u-boot commandline working with long commands
sending to the board.
Since the above patch, you have to setup the fcr register.
For board/archs which enable OF_PLATDATA, the new field
fcr in struct ns16550_platdata is not filled with a
default value ...
This leads in not setting up the uarts fifo, which ends
in problems, when you send long commands to u-boots
commandline.
Detected this issue with automated tbot tests on am335x
based shc board.
The error does not popup, if you type commands. You need
to copy&paste a long command to u-boots commandshell
(or send a long command with tbot)

Add driver data to each compatible string to identify the type of
the port. Since all the ports in the driver are entirely compatible
with 16550 for now, all are marked with PORT_NS16550. But, there
are ports which have specific quirks, like the JZ4780 UART, which
do not have any DT property to denote the quirks. Instead, Linux
uses the compatible string to discern such ports and enable the
necessary quirks.
