[Qemu-commits] [COMMIT 47d37dd] vga: split pci bits into vga-pci.c


From: Anthony Liguori
Subject: [Qemu-commits] [COMMIT 47d37dd] vga: split pci bits into vga-pci.c
Date: Wed, 09 Sep 2009 22:36:35 -0000

From: Juan Quintela <address@hidden>

Adjust all the VGAState in VGACommonState
Compile vga-pci.o only for targets that use it.
