Subject: drm/nouveau: fix nv30 pcie boards
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=01d153326ecd81ed77395f1699a30af416cf77ab;p=openwrt%2Fstaging%2Fblogic.git

drm/nouveau: fix nv30 pcie boards

Wasn't aware they even existed, apparently they do!  They're actually
AGP chips with a bridge as far as I can tell, which puts them in the
same boat as nv40/nv45.
