30 * A list of boot stages that we know about. Each of these indicates the
31 * state that we are at, and the action that we are about to perform. For
32 * errors, we issue an error for an item when it fails. Therefore the
39 * and an error condition where action 3 failed would be:
47 BOOTSTAGE_ID_RUN_OS = 15, /* Exiting U-Boot, entering OS */
51 * Board code can implement show_boot_progress() if needed.
53 * @param val Progress state (enum bootstage_id), or -id if an error
56 void show_boot_progress(int val);
