- * init_ide_data() sets reasonable default values into all fields
- * of all instances of the hwifs and drives, but only on the first call.
- * Subsequent calls have no effect (they don't wipe out anything).
- *
- * This routine is normally called at driver initialization time,
- * but may also be called MUCH earlier during kernel "command-line"
- * parameter processing.  As such, we cannot depend on any other parts
- * of the kernel (such as memory allocation) to be functioning yet.
- *
- * This is too bad, as otherwise we could dynamically allocate the
- * ide_drive_t structs as needed, rather than always consuming memory
- * for the max possible number (MAX_HWIFS * MAX_DRIVES) of them.
- *
- * FIXME: We should stuff the setup data into __init and copy the
- * relevant hwifs/allocate them properly during boot.
