Stack Size Analysis Tool for EC Firmware

This tool does static analysis on EC firmwares to get the maximum stack usage of each function and task. The maximum stack usage of a function includes the stack used by itself and the functions it calls.

Usage

Make sure the firmware of your target board has been built.

In src/platform/ec, run

make BOARD=${BOARD} SECTION=${SECTION} ANNOTATION=${ANNOTATION} analyzestack

The ${SECTION} can be RO or RW. The ${ANNOTATION} is a optional annotation file, see the example_annotation.yaml.
