Drop CONFIG_LPUART_32B_REG.
Move the register structure to a common file include/fsl_lpuart.h
Define lpuart_serial_platdata structure which includes the reg base and flags.
For 32Bit register access, use lpuart_read32/lpuart_write32 which handles
big/little endian.
For 8Bit register access, still use the orignal code.

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.

Previously ns16550 compatible UARTs probed via device tree have needed
their device tree nodes to contain a clock-frequency property. An
alternative to this commonly used with Linux is to reference a clock via
a phandle. This patch allows U-Boot to support that, retrieving the
clock frequency by probing the appropriate clock device.
For example, a system might choose to provide the UART base clock as a
reference to a clock common to multiple devices:
sys_clk: clock {
compatible = "fixed-clock";
#clock-cells = <0>;
clock-frequency = <10000000>;
};
uart0: uart@10000000 {
compatible = "ns16550a";
reg = <0x10000000 0x1000>;
clocks = <&sys_clk>;
};
uart1: uart@10000000 {
compatible = "ns16550a";
reg = <0x10001000 0x1000>;
clocks = <&sys_clk>;
};
This removes the need for the frequency information to be duplicated in
multiple nodes and allows the device tree to be more descriptive of the
system.

On the raspberry pi, you can disable the serial port to gain dynamic frequency
scaling which can get handy at times.
However, in such a configuration the serial controller gets its rx queue filled
up with zero bytes which then happily get transmitted on to whoever calls
getc() today.
This patch adds detection logic for that case by checking whether the RX pin is
mapped to GPIO15 and disables the mini uart if it is not mapped properly.
That way we can leave the driver enabled in the tree and can determine during
runtime whether serial is usable or not, having a single binary that allows for
uart and non-uart operation.

Commit 83fd908f28c ("dm: imx: serial: Support DTE mode when using driver
model") breaks the serial output for the imx boards that do not use
the serial driver model.
The reason for the breakage is that it's setting UFCR_DCEDTE
unconditionally for the non-dm case.
So keep the original behavior by removing UFCR_DCEDTE setting in the
non-dm case.
