+Subject: [PATCH 1/5] libweston: Restore EGL support for the fbdev backend
+
+In Weston 2.0, the EGL support was dropped from the fbdev-backend,
+as that was not the correct way to initialize the EGL in first
+place. However, the vendor support patches in Weston 1.11 still
+require that functionality. Teporary restore the EGL support in
+the fbdev-backend, until a separate vendor backend is available,
+or switch to using etnaviv.
+
