Migrate boards from static /etc/passwd files to build-time generation:
* Remove static etc/passwd files from SIM and ESP32-C3-legacy boards
* Update board configurations to enable BOARD_ETC_ROMFS_PASSWD_ENABLE
* Configure SIM board with login demo user (root/Administrator)
* Update board build rules to use newly generated passwd files
* Remove CMakeLists.txt dependency on static passwd in SIM
* Update MOTD string from username=admin to username=root
This completes the infrastructure migration for boards supporting
login functionality.
BREAKING CHANGE: The static etc/passwd files have been removed from
boards/sim/sim/sim/src/etc/passwd
boards/risc-v/esp32c3-legacy/esp32c3-legacy-devkit/src/etc/passwd
These boards now require CONFIG_BOARD_ETC_ROMFS_PASSWD_ENABLE=y and a
configured password. Any board carrying a custom static passwd file must
set RCRAWS to exclude etc/passwd and manage credentials via the new
Kconfig options or provide their own passwd generation. To fix: run
'make menuconfig' and navigate to:
Board Selection --->
Auto-generate /etc/passwd at build time --->
Admin password

Introduce mkpasswd, a pure-C host tool for generating encrypted password
files at build time using TEA encryption. This enables secure,
credential-free firmware images while allowing build-time password
configuration.
Changes:
* Add mkpasswd.c host tool for TEA-based password hashing and encryption
* Integrate mkpasswd into Make build system (tools/Makefile.host)
* Add CMake support for mkpasswd compilation and ROMFS passwd generation
* Add CONFIG_BOARD_ETC_ROMFS_PASSWD_* configuration options to Kconfig
* Implement credential exclusion from defconfig to prevent password leaking
* Update savedefconfig.cmake to strip sensitive credentials
* Fix mkdir() portability for Windows Native builds (CONFIG_WINDOWS_NATIVE)
* Change default username from "admin" to "root" (POSIX convention)
* Improve build-failure error message with full menuconfig navigation path
BREAKING CHANGE: Boards enabling CONFIG_BOARD_ETC_ROMFS_PASSWD_ENABLE
must set CONFIG_BOARD_ETC_ROMFS_PASSWD_PASSWORD to a non-empty string
of at least 8 characters. The build now fails with an explicit error if
this config is left empty. To fix: run 'make menuconfig' and navigate to:

When both CONFIG_ESP32_SPIRAM and CONFIG_ESP32_SPIRAM_USER_HEAP
are selected, the device must not select CONFIG_NSH_ARCHINIT.
Instead, CONFIG_BOARD_LATE_INITIALIZE must be selected. This is
necessary because the SPI flash initialization disables the cache,
and only internal memory is then accessible. So, if the SPI flash
initialization is performed by the entry task (nsh_main, a regular
task), it would use the user heap to allocate memory, which would
cause a system crash when the cache is disabled. On the other hand,
by selecting CONFIG_BOARD_LATE_INITIALIZE, a kernel thread is
dedicated to perform the initialization, and the cache can be
safely disabled.

Fix several issues preventing the protected build from booting:
memory.ld: Increase ksram from 16K to 20K to accommodate kernel
BSS and idle thread stack. Rebalance usram to 20K and xsram to
24K accordingly.
defconfig: Remove CONFIG_FS_TMPFS to reduce kernel binary size
so it fits within the 128KB kflash partition.
defconfig: Add CONFIG_TLS_LOG2_MAXSTACK=11 to reduce TLS stack
alignment from 8K(default) to 2K. The default 8K alignment
caused memalign to request oversized allocations from the
user heap, failing the init task stack allocation.

debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.
A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

The common ESP board RMT bring-up files are built whenever ESP_RMT is

is enabled.
Guard the esp_lirc header include and esp_lirc_rx_initialize() /
esp_lirc_tx_initialize() calls with CONFIG_DRIVERS_RC so non-RC ESP
configs continue to build while keeping the LIRC registration path for

Replace the ESP-specific rmtchar upper-half with arch-local esp_lirc
adapters for Xtensa and RISC-V.
This moves the RMT upper-half out of drivers/rmt, registers LIRC
devices from the ESP board bring-up paths, and removes the old common
rmtchar driver and headers.
Also update the ESP Kconfig and build wiring to build esp_lirc when
ESP_RMT and DRIVERS_RC are enabled.
Fixes discovered during hardware validation:
- register TX as /dev/lirc1 so RX and TX do not collide
- parse the RX worker thread argument from the correct argv slot
- keep RX devices from advertising TX capability

This commit updates the common-source integration for Xtensa-based
Espressif devices (ESP32, ESP32-S2, and ESP32-S3). This is part of a larger
common-source update split by architecture for better maintainability.
Major components updated:
- IRQ allocator refactoring with intr_alloc integration
- Common-source drivers (GPIO, RMT, I2C, SPI, UART, etc.)
- Espressif components upgrade to release/master.b-test
- Peripheral drivers (ADC, PWM, LEDC, MCPWM, PCNT, Temperature Sensor, etc.)
- Wireless adapters (Wi-Fi and BLE)
- esp_timer migration to the common-source path for Xtensa devices
- Common-source power management implementation (auto-sleep and wakeup paths)
- Board defconfigs for all Xtensa Espressif boards
- SMP support improvements for ESP32-S3
- Critical section handling improvements
Key architectural changes:
- IRQ Allocator: The new interrupt allocator enables multiple mapping
options from interrupt sources to CPU interrupts, providing flexibility
required by modern peripherals. Although this introduces breaking changes
to the interrupt handling API, the required ARCH_MINIMAL_VECTORTABLE
Kconfig option is explicitly checked during startup to ensure proper
configuration. This validation prevents runtime issues from configuration
mismatches.
- Xtensa-specific interrupt handling via esp_xtensa_intr.c providing
NuttX-native implementations of xt_ints_on/off and interrupt handlers,
avoiding conflicts with NuttX's core Xtensa macros.
- Timer/RTC unification: ESP32/ESP32-S2/ESP32-S3 move from chip-specific
RTC/RT-timer code to common-source Espressif integration, including
esp_timer_adapter/esp_rtc paths and the required bringup/defconfig updates.
- Power management consolidation: Xtensa PM follows the common-source
implementation, including common-source auto-sleep behavior, UART/Wi-Fi
wakeup coordination, and tickless-safe sleep flow compatibility.
Note: This is a large commit to maintain bisectability. Breaking the
changes into smaller commits would result in non-building intermediate
states across the common-source infrastructure update.
Tested configurations:
- All defconfigs were tested, including `ostest`.
