Doing a squash merge to avoid having the `slc_cli_linux` .zip files in the history. They were added in one commit and removed and replaced with a submodule in another. * Initial commit for xg24 * Fix SLC issue * Fix SLC extract fail * Change board's name * Correct spelling of code Build immediately after slc generate * Remove VID and PID * Change creator and creation id * Apply new creator_id and creation_id * Update makefile, error message, mcu_processor function * Update mpconfigboard.mk * Update Board extensions, PORT_DEPS * Update makefile * Add exclude_patterns * Show java, jinja2 version * Show path for debugging CI * Add requirements-dev for slc * Add PATH slc_cli * Update background function * Add jinja2 PATH * Show PATH * Update jinja2 path * Update jinja2 path * Update jinja2 path * Update jinja2 path * Change slc folder * Change markupsafe folder * Add symbolic link for slc * Update makefile * Update makefile * Update MX25R3235F.toml from submodule nvm.toml * alphabetize the list * Remove slc_cli_linux folder * Update slc_cli submodule --------- Co-authored-by: Chat Nguyen <cvnguyen@silabs.com> Co-authored-by: silabs-ChatNguyen <chat.nguyen@silabs.com> Co-authored-by: silabs-ChatNguyen <126220343+silabs-ChatNguyen@users.noreply.github.com>
