From 6103451aeb749e92bf7d730429985189c6921c32 Mon Sep 17 00:00:00 2001 From: Phil Dennis-Jordan Date: Wed, 15 Mar 2017 19:20:27 +1300 Subject: hw/i386: Build-time assertion on pc/q35 reset register being identical. This adds a clarifying comment and build time assert to the FADT reset register field initialisation: the reset register is the same on both machine types.
