From d7b0c143693bcbf391d2be235e150b97bfd8f9ba Mon Sep 17 00:00:00 2001 From: Saeed Bishara Date: Sun, 6 Dec 2009 18:26:17 +0200 Subject: sata_mv: increase PIO IORDY timeout The old value (0xbc) in cycles of the IORDY timeout is suitable for devices with core clock of 166 MHz, but some SoC controllers have faster core clocks. The new value will make the IORDY timeout large enough also for all SoC devices.
