The WiFi driver refactor (662c1e0bbb) renamed the Kconfig symbol
from CONFIG_ESPRESSIF_WLAN to CONFIG_ESPRESSIF_WIFI, but several
ESP32-S3 board bringup files were not updated. This caused
board_wlan_init() to be compiled out, so the wlan0 interface
never appeared.

- esp32s3-eye
- esp32s3-korvo-2
- esp32s3-lcd-ev
- lckfb-szpi-esp32s3

Ignore unsupported telnet subnegotiation payload until `IAC SE` so
option bytes do not leak into the first NSH command.
Keep existing NAWS handling intact and also treat `IAC IAC` inside
subnegotiation payload as an escaped `0xFF` data byte rather than a
subnegotiation terminator.
This makes subnegotiation parsing RFC-compliant for both unsupported
options and NAWS payload processing.

Remove the unnecessary CONFIG_RPMSG_UART_CONSOLE preprocessor guard around
the console registration logic in uart_rpmsg_init().
The uart_rpmsg_init() function already accepts a bool isconsole parameter to
dynamically control console registration, which is designed to support flexible
console setup in distributed multi-core SOC systems. Adding the macro check on
top of this runtime parameter is redundant and negates the dynamic registration
capability.
This change fixes a regression introduced by PR #18410, which broke the functionality
of sim/rpproxy and sim/rpserver due to the incorrect macro guard preventing proper
console registration for the rpmsg UART device.

If power down mode is set, trying to read ID ends in an infinite loop
because w25_waitwritecomplete never returns as status register never
signalizes write complete. Therefore ensure the device is not in a
power down mode before trying to read from it.
This can be an issue if the board is trying to check for more NOR
memories on one SPI bus and one chip select. For example GD25 driver
returns the memory to power down state after read id is finished,
therefore board initialization is stuck in an infinite loop if it first
checks for GD25 and then fallbacks to W25.
The commit fixes the possible issue by ensuring W25 is brought back
to normal operation mode before trying to obtain the manufacturer ID.

This patch adds defconfig example to The Custom Boards How-To guide.
The command specified in this guide which runs configure script fails
if the defconfig file does not exists; the guide did not mention this
file at all.
If the file exists but is empty, the configure script fails and leaves
the system in a broken state which is somewhat difficult to deal with.
(Subsequent attempts to configure fail but so do attempts to distclean.)
To resolve this, this patch adds a minimal defconfig example which
should be sufficient for the configure script to do its work correctly.

Use NVIC_IRQ_ENABLE(n) and NVIC_IRQ_PRIORITY(n) macros in

The X11 event loop in the POSIX simulator was processing MotionNotify
(touch/mouse movement)and ButtonPress/ButtonRelease events unconditionally,
even when the touchscreen feature(CONFIG_SIM_TOUCHSCREEN) was disabled.
This could lead to unnecessary event processing, potential compiler warnings
about unusedfunctions (e.g., sim_buttonevent), or unintended behavior in simulator
builds withouttouchscreen support. The touchscreen-related event handling should
only be active whenthe corresponding configuration is enabled.
This fix wraps the MotionNotify and ButtonPress/ButtonRelease event handling
logicwith #ifdef CONFIG_SIM_TOUCHSCREEN guards to:
1. Ensure touchscreen/mouse event processing is only compiled when CONFIG_SIM_TOUCHSCREEN is enabled.
2. Eliminate unused code warnings in non-touchscreen simulator builds.
3. Align event loop behavior with the configured feature set, reducing unnecessary runtime overhead.
The change maintains full touchscreen functionality when the config is enabled, whilecleaning up the
code path for builds that don't require touchscreen support.

The X11 framebuffer implementation in the POSIX simulator was creating a window
and graphics context but failing to map (display) the window to thescreen with XMapWindow().
This omission meant the framebuffer window would be created in the X11server but remain hidden,
making it impossible to see any graphics outputfrom the simulator. The window existed in the X11
server's state but wasnot rendered to the screen.
This fix adds the missing XMapWindow(display, g_window) call aftercreating the graphics context, which:
1. Maps the created X11 window to the screen (makes it visible).
2. Ensures framebuffer output is rendered to the display as expected.
3. Maintains compatibility with existing X11 framebuffer logic.
The change restores basic visibility of the simulator's framebuffer window,
fixing a critical usability issue for graphics-related testing in the POSIX simulator.

This commit introduces a new Kconfig option LIBC_MUTEX_BACKTRACE_SKIP tocontrol the
number of initial addresses skipped when generating mutex backtraces.
Key changes:
1. Add LIBC_MUTEX_BACKTRACE_SKIP Kconfig entry (depends on
LIBC_MUTEX_BACKTRACE > 0), defaulting to 2. This option lets users configure
how many leading addresses are omitted from the mutex backtrace output.
2. Modify the nxmutex_add_backtrace() function to pass the new config value
as the skip parameter to sched_backtrace(), replacing the hardcoded 0.
This enhancement improves the usability of mutex backtraces by allowing removalof uninformative
initial stack frames (e.g., backtrace helper functions ormutex acquisition wrappers), making the
relevant call stack entries more visiblefor debugging lock-related issues.
The default value (2) maintains sensibleout-of-the-box behavior while enabling customization for specific use cases.
