+Subject: [PATCH] libata: add waits for GoVault
+References: 246451
+
+Iomega GoVault drives need specific waits here and there.  Upstream
+approach hasn't been determined yet.  This is temp solution from Gary
+Hade.  Read the following thread for details.
+
+http://thread.gmane.org/gmane.linux.ide/14545/focus=14663
+
+With recent changes in the reset sequence (ATA_TMOUT_FF_WAIT and
+prefer-hardreset), the only thing which needs adjustment is
+ATA_TMOUT_FF_WAIT (the prereset wait part is unnecessary as the wait
+is necessary only for softreset when SCR registers are accessible and
+in those cases libata now always uses hardreset which doesn't require
+such wait).
