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`.

This adds new fields to the metadata section used by MCUBoot.
The openocd-esp32 project requires these fields to properly map the
flash segments and enable using SW breakpoints and flash through
openocd-esp32.

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

The Simple Boot feature for Espressif chips is a method of booting
that doesn't depend on a 2nd stage bootloader. Its not the
intention to replace a 2nd stage bootloader such as MCUboot and
ESP-IDF bootloader, but to have a minimal and straight-forward way
of booting, and also simplify the building.
This commit also removes deprecated code and makes this bootloader
configuration as default for esp32s2 targets and removes the need
for running 'make bootloader' command for it.
