- * vt6420_prereset - prereset for vt6420
- * @ap: target ATA port
- *
- * SCR registers on vt6420 are pieces of shit and may hang the
- * whole machine completely if accessed with the wrong timing.
- * To avoid such catastrophe, vt6420 doesn't provide generic SCR
- * access operations, but uses SStatus and SControl only during
- * boot probing in controlled way.
- *
- * As the old (pre EH update) probing code is proven to work, we
- * strictly follow the access pattern.
- *
- * LOCKING:
- * Kernel thread context (may sleep)
- *
- * RETURNS:
- * 0 on success, -errno otherwise.
