From: Tejun Heo Date: Wed, 7 Feb 2007 12:37:41 -0800 Subject: [PATCH] libata: add waits for GoVault References: 246451 Patch-mainline: not yet 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).
