| 3 | Subject: [PATCH] libata: add waits for GoVault | |
| 4 | References: 246451 | |
| 5 | ||
| 6 | Iomega GoVault drives need specific waits here and there. Upstream | |
| 7 | approach hasn't been determined yet. This is temp solution from Gary | |
| 8 | Hade. Read the following thread for details. | |

| 12 | With recent changes in the reset sequence (ATA_TMOUT_FF_WAIT and | |
| 13 | prefer-hardreset), the only thing which needs adjustment is | |
| 14 | ATA_TMOUT_FF_WAIT (the prereset wait part is unnecessary as the wait | |
| 15 | is necessary only for softreset when SCR registers are accessible and | |
| 16 | in those cases libata now always uses hardreset which doesn't require | |
| 17 | such wait). | |
