Pull request overview

Updates the benchmarking and emulation tooling to support running boot-time benchmarks from a Raspberry Pi against an STM32H5/H563 target, plus associated build/config tweaks to enable consistent timing and sizing measurements.

Changes:

  • Add a new libgpiod-based boot-time measurement script and switch the benchmark runner to OpenOCD + GPIO edge timing.
  • Introduce build flags (WOLFBOOT_TEST_FILLER, WOLFBOOT_TIME_TEST) and early-boot GPIO toggling to support boot-time measurements.
  • Adjust emulation linker templates and config-generation flow for multiple targets (STM32*, nRF, MCX).

test-app/ARM-stm32h5-ns.ld Increase RAM size in non-secure linker script template.
src/image.c Silence unused stored_secondary_signature_size.
options.mk Add build flags for timing/filler; adjust ECC521 stack usage number.
include/image.h Add an extra compare_res; statement inside RSA verification macro.
