Pull request overview
This PR fixes the STM32N6 IAR build by updating linker script paths and adding missing CMSE (Cortex-M Security Extensions) compiler flags. The STM32N6 family uses Cortex-M55 with TrustZone security features and requires FSBL (First Stage Boot Loader) configuration targeting AXISRAM2.
- Updated linker script references from
_flashto_axisram2_fsblvariants for both GNU and IAR toolchains - Added CMSE compiler flags (
-mcmsefor Clang,--cmsefor IAR) to align with existing GCC configuration
