Subject: vga: allow non-global vmstate
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~874^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e2bbfc8ee2aa82519da7de281305c3bea5431cf1;p=sdk%2Femulator%2Fqemu.git

vga: allow non-global vmstate

Need a way to opt-out from vga.vram being global vmstate, for
secondary vga cards.  Add a bool parameter to vga_common_init
to support this.
