b29dbf98ba x86: Allow locating the UART from ACPI tables
When coreboot does not pass a UART in its sysinfo struct, there is no
easy way to find it out.

Since coreboot does not actually init the serial device when serial is
disabled, it is not possible to make it add this information to the
sysinfo table.

Add a way to obtain this information from the DBG2 ACPI table, which is
normally set up by coreboot.

For now this only supports a memory-mapped 16550-style UART.

10ea2a7a93 serial: msm-geni: correct oversampling value based on QUP hardware revision
Starting from QUP v2.5 the value of oversampling is changed from 32
to 16, keeping the old value on newer platforms results on wrong set
UART IP clock divider, thus the asked baudrate does not correspond to
the actually set with all the consequencies for a user.

The change links the driver to a new Qualcomm GENI SE QUP driver
to get its hardware version and update the oversampling value.

Deliberately the code under CONFIG_DEBUG_UART_MSM_GENI is not touched,
since a wanted baudrate can be controlled by setting a modified
CONFIG_DEBUG_UART_CLOCK build time variable.

836d1bfffa serial: sh: Add DEBUG_UART support
Add support for debug output very early during boot using the DEBUG_UART
mechanism. This uses a static fixed UART port configuration selected via
Kconfig options and dedicated print functions from debug_uart.h. This is
useful e.g. when debugging problems so early during boot, that not even
the DM is initialized at that point, and thus DM_SERIAL is not available
either.

This functionality is disabled by default. To activate it, define the
following Kconfig options and select SCIF type using CFG_SCI/CFG_SCIF_A/
CFG_HSCIF/<nothing for regular SCIF>:

CONFIG_DEBUG_UART=y
CONFIG_DEBUG_UART_SCIF=y
CONFIG_DEBUG_UART_BASE=0xe6540000
CONFIG_DEBUG_UART_CLOCK=24000000

The later two options define the SCIF physical base address and SCIF
input clock in Hz. Optionally, to validate DEBUG_UART works, enable
the following as well to get early serial output message by default:

CONFIG_DEBUG_UART_ANNOUNCE=y

7a76347189 serial: dm: Add support for puts
Some serial drivers can be vastly more efficient when printing multiple
characters at once. Non-DM serial has had a puts option for these sorts
of drivers; implement it for DM serial as well.

Because we have to add carriage returns, we can't just pass the whole
string directly to the serial driver. Instead, we print up to the
newline, then print a carriage return, and then continue on. This is
less efficient, but it is better than printing each character
individually. It also avoids having to allocate memory just to add a few
characters.

Drivers may perform short writes (such as filling a FIFO) and return the
number of characters written in len. We loop over them in the same way
that _serial_putc loops over putc.

This results in around sizeof(void *) growth for all boards with
DM_SERIAL. The full implementation takes around 140 bytes.

74d11d37e2 serial: Add semihosting driver
This adds a serial driver which uses semihosting calls to read and write
to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled,
we will instantiate a serial driver. This allows users to enable this
driver (which has no physical device) without modifying their device
trees or board files. We also implement a non-DM driver for SPL, or for
much faster output in U-Boot proper.

There are three ways to print to the console:

Method              Baud
================== =====
smh_putc in a loop   170
smh_puts            1600
smh_write with :tt 20000
================== =====

These speeds were measured using a 175 character message with a J-Link
adapter. For reference, U-Boot typically prints around 2700 characters
during boot on this board. There are two major factors affecting the
speed of these functions. First, each breakpoint incurs a delay. Second,
each debugger memory transaction incurs a delay. smh_putc has a
breakpoint and memory transaction for every character. smh_puts has one
breakpoint, but still has to use a transaction for every character. This
is because we don't know the length up front, so OpenOCD has to check if
each character is nul. smh_write has only one breakpoint and one memory
transfer.

DM serial drivers can only implement a putc interface, so we are stuck
with the slowest API. Non-DM drivers can implement puts, which is vastly
more efficient. When the driver starts up, we try to open :tt. Since
this is an extension, this may fail. If it does, we fall back to
smh_puts. We don't check :semihosting-features, since there are
nonconforming implementations (OpenOCD) which don't implement it (but
*do* implement :tt).

Some semihosting implementations (QEMU) don't handle READC properly. To
work around this, we try to use open/read (much like for stdin) if
possible.

There is no non-blocking I/O available, so we don't implement pending.
This will cause __serial_tstc to always return true. If
CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read
characters forever. To avoid this, we depend on this config being
disabled.

384d5cfe5d serial: serial_xen: Add Xen PV serial driver
Add support for Xen para-virtualized serial driver. This
driver fully supports serial console for the virtual machine.

Please note that as the driver is initialized late, so no banner
nor memory size is visible.

4cc24aeaf4 serial: Add missing Kconfig dependencies for debug consoles
Debug console is the part of serial driver in the same file. It means to be
able to enable debug console you also need to enable driver itself.
That's why add all dependecies and list only debug consoles which are
enabled based on driver selection to avoid compilation error when user
asks for certain debug console but driver is not enable for it.

Error:
