From ab46c15f61844b62ded575d5710fe2da0cae32d8 Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Tue, 31 Jan 2012 22:40:50 +0100 Subject: [PATCH] i3100: Add init sequence i3100 misses the magic SATA init sequence, which makes all requests fail. Captured from the vendor BIOS, which writes those bits on all configurations.
