From a0ce9aca97ccf71dc969b44a4c9b3c36da0be362 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 19 Nov 2007 12:06:37 +0900 Subject: [PATCH] ata_piix: port enable for the first SATA controller of ICH8 is 0xf not 0x3 ICH8 and 9 use two SFF controllers to show 6 SATA ports. The first controllre hosts the first 4 ports while the second one hosts the last 2. The PCS register of the first controller encompasses the first four ports or all six ports depending on configuration while PCS of the second controller controls the last two ports. Using 0xf for the first controller and 0x3 for the second controller always result in the correct configuration.
