From 5eb81bed2ea503aaf910430da492ed75d27ef94f Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Thu, 10 Jan 2019 23:13:11 +0100 Subject: sb/intel/i82801gx: Detect if the southbridge supports AHCI This automatically detects whether the southbridge supports AHCI. If AHCI support is selected it will be used unless "sata_no_ahci" is set in the devicetree to override the behavior.
