I've been working on the gfx-device hand-over with SimpleDRM for some
time now. I fully agree with Hans. This has to be a per-device
hand-over. This works totally fine on x86 already and it should be
easy to get done for other devices. I have ported SimpleDRM to
non-VESA drivers and it works just fine, and I'm open to rename it to
firmware-drm / fwdrm / whatever and add real hardware support.
simplefb was meant to be hw-agnostic, so I understand that Stephen
doesn't want to extend it. But before we start adding more fbdev
drivers, I honestly think we should at least try pushing such a DRM
driver upstream.

I will be talking about this at XDC this week, and in the
Wayland-microconf at Plumbers. I am open for discussion. If people
want this, I can refresh my sysfb+simpledrm series and send a pull
request to Dave. He was already willing to merge it, but I wanted to
cleanup the drm BKL first..

Thanks
David
