feat(bt): Support Bluetooth LE and Bluetooth Classic on ESP32-S31
Closes IDF-15185, IDF-15188, IDF-15189, IDF-15193, and IDF-15192
See merge request espressif/esp-idf!47330
- feat(soc_caps): Enable BT Classic and BLE in esp32s31
- Add git submodule for ESP32-S31 bt controller lib files
- changed sdkconfig.defaults and README for Bluetooth Classic examples
- change(docs): Added vendor HCI documentations for ESP32-S31
- change(Bluedroid): Adapt to ESP32-S31 due to some API differences on
Bluetooth controller from ESP32
- change(bt): Modify CMakeLists.txt to support the Bluetooth dual-mode
architecture on ESP32-S31
- change(bt): Add ECC P-192 functions to tinycrypt
fix(esp_log): Add Kconfig option to disable usage of esp_rom_vprintf when this function is in IRAM and not ROM

Add a new CMake function esp_partition_flash_binary() that provides a
unified API for registering partition data binaries to be flashed. It
replaces the direct esptool_py_flash_target calls scattered across
components (spiffs, fatfs, nvs_flash) with a single function that:
- Resolves partition offset from the partition table automatically
- Determines encryption requirements (auto-detect or ALWAYS_PLAINTEXT)
- Creates per-partition flash targets (e.g. idf.py <partition>-flash)
- Optionally includes the binary in `idf.py flash` via FLASH_IN_PROJECT
On the linux target, the function registers binaries for pre-loading
into the emulated flash. A build-time manifest (linux_flash_data.txt)
is generated via file(GENERATE), and partition_linux.c reads it at
runtime to copy each binary into the memory-mapped flash buffer at
the correct offset.
The partition_ops example is updated to use the new function and
includes a custom_partition with pre-built data to demonstrate the
full workflow, including on the linux target.
Add ESP32-S31 USB DWC/UTMI LL headers, SoC register structures, peripheral
descriptors, capabilities, and linker mappings so the HS OTG controller and
UTMI PHY can be built in esp_hal_usb.
Introduce SOC_USB_FSLS_PHY_NUM on USB-OTG targets to separate FSLS USB_WRAP
support from OTG/UTMI support. Use it to gate usb_wrap, the USB PHY driver,
docs, and example build rules on targets without an FSLS PHY.
Also add UTMI data pulldown control to the HAL, clear the boot-time DWC
suspend state on ESP32-S31, alias the legacy internal PHY target to UTMI for
backward compatibility, and extend usb_phy tests for UTMI-only targets.
In Log V2, ESP_LOG macros are using the runtime
constrained-environment path in esp_log_vprintf() reference
esp_rom_vprintf as the fallback formatter. On chips where ets_vprintf
is not in ROM (all targets except ESP32-S2 and ESP32-C2), this pulls
~1.2 KB of printf implementation into IRAM.
Add a new Kconfig option LOG_API_CONSTRAINED_ENV_SAFE (default y) that
controls whether this IRAM-resident fallback is used:
Also update the logging and RAM-usage documentation accordingly.
