wolfSSL STM32CubeMX2 (MX2) codegen assets

STM32CubeMX2 replaces the classic CubeMX pack mechanism: the configuration GUI is defined by a JSON-Forms schema and the configuration header is rendered by a Handlebars template through cube codegen, producing mx_wolfSSL_conf.h in the generated project (the MX2 analog of wolfSSL.I-CUBE-wolfSSL_conf.h, using the same WOLF_CONF_* scheme).

• mx_wolfSSL_parameters.json - the wolfSSL configuration panel shown in STM32CubeMX2 (JSON-Forms). Includes the STM32 Hardware Crypto toggle: on devices where wolfSSL has register-level STM32 support (independent of the HAL1 to HAL2 API change), the generated configuration enables the RNG, HASH, AES and PKA peripherals.
• mx_wolfSSL_conf_template.h.hbs - the Handlebars template that renders mx_wolfSSL_conf.h.

wolfssl/wolfcrypt/settings.h includes the generated header when WOLFSSL_MX2_CONF_INCLUDE is defined. HAL2 projects have no global define like HAL1's USE_HAL_DRIVER, so the pack's configuration component declares that macro through the generated Pre_Include_Global.h that STM32CubeMX2 force-includes. A project that adds these sources by hand, without the pack, must define WOLFSSL_MX2_CONF_INCLUDE itself.

These files are packaged into the wolfSSL.wolfSSL_middlewares pack for STM32CubeMX2 by the wolfSSL pack tooling; the pack build prefers the copies in this directory so the configuration stays versioned with the library.

Project checklist (validated on NUCLEO-C5A3ZG, full wolfcrypt_test pass)

• Enable the console UART (Async) matching the wolfSSL panel's Console UART instance (default usart2, the Nucleo VCP) and enable the RNG peripheral so the generated clock init arms the RNG kernel clock.
• Raise HEAP_SIZE/STACK_SIZE in the project's user_modifiable linker script (128 KB / 16 KB recommended); the defaults are too small for wolfSSL and fail wolfcrypt_test's MEMORY test.
• Call wolfCryptDemo(NULL) (from wolfssl_example.c, the wolfCrypt Test component) in main() to get the interactive test/benchmark menu on the console UART; printf is retargeted through the syscalls utility's __io_putchar hook automatically.
• For benchmark throughput output add -u _printf_float to the linker options (newlib-nano) and build the Release profile.
