Subject: hw/display: Remove "rombar" hack from vga-pci and vmware_vga
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=97d8381543647887bc2997ecfeccc67831e47fdc;p=qemu.git

hw/display: Remove "rombar" hack from vga-pci and vmware_vga

Now that the old pc-0.x machine types have been removed, we do not need
the old "rombar" hacks anymore.
