This patch introduces a weak default function for post_hotkey_pressed(), returning 0, for boards without hotkey support. The long-running tests won't be started on those boards. This default function was implemented in many board directories. By implementing this weak default we can remove all those duplicate versions. Boards with hotkey support, can override this weak default function by defining one in their board specific code. Signed-off-by: Stefan Roese <sr@denx.de>
