Pull request overview
Adds STM32U3 platform wiring so existing STM32 hardware-acceleration code paths (AES, HASH/HMAC, RNG) can be enabled for STM32U3 targets, primarily in STM32Cube/CubeMX configurations.
Changes:
- Add
WOLFSSL_STM32U3to STM32 platform detection insettings.h, including CubeMX HAL include and AES-192 disablement for HW crypto. - Extend STM32 port feature-detection macros to treat
WOLFSSL_STM32U3like other STM32 families for AES-GCM / HAL v2 selection. - Update STM32CubeMX template and README to allow enabling STM32U3 (tested with
STM32U385xx).
