From 7fb6577b130c615e42e1ccf8dad69c27c3eef085 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Tue, 1 Feb 2011 15:51:28 +0100 Subject: ahci: split ICH and AHCI even more Sebastian's patch already did a pretty good job at splitting up ICH-9 AHCI code and the AHCI core. We need some more though. Copyright was missing, the lspci dump belongs to ICH-9, we don't need the AHCI core to have its own qdev device duplicate. So let's split them a bit more in this patch, making things easier to read an understand.
