From 647e385187767d63ca0d5d2b2f0f27bffecaa5a5 Mon Sep 17 00:00:00 2001 From: Damien Zammit Date: Fri, 15 Jan 2016 13:44:53 +1100 Subject: sb/intel/i82801gx: Fix sata AHCI for desktop NM10/ICH7 Tested on Intel D510MO Before this patch, I was unable to get the SATA controller into AHCI mode. That is, I could never see PCI ID 8086:27c1 appearing on the bus. With sata_ahci set, controller now goes into AHCI mode and works. 8086:27c1 Tested on X60 with AHCI enabled 8086:27c5 (AHCI mode for mobile ich7) No regressions detected.
