Subject[PATCH] drm/msm: Transition console to msm framebuffer
Date
If booting a device using EFI, efifb will likely come up and claim the
console. When the msm display stack finally comes up, we want the
console to move over to the msm fb, so add support to kick out any
firmware based framebuffers to accomplish the console transition.
