* ch552 firmware: add ch55x support files directly * Add sdcc compiler to docker image, for building CH552 firmware * Rework production test script * Add menu-based test runner * Rewrite production test flows as lists of individual tests * Add both production flows and manual tests to menu * Switch to using included binaries * production test: Update message format * test_txrx_touchpad: Retry if device communications fail * production test: put all binaries in binaries/ folder * binaries/top.bin: replace broken binary * flash_check: Check for explicit flash IDs * Document most test procedures * Test plan documentation * Sample udev rules * Production test: allow external references to be overridden * Remove outdated descriptions * Correct shebang * Update shebangs to comply with PEP 394 Change the python scripts to call python instead of python3, as this works cross platform. See: https://peps.python.org/pep-0394/#for-python-script-publishers * Move production test to higher-level directory * Clarify production test setup * Move USB C connector test to separate directory Co-authored-by: Michael Cardell Widerkrantz <mc@tillitis.se>
