Doens't simplefb itself check the existence and status in the dtb ?
AFAIK I have simplefb in my kernel, but u-boot doesn't configure it,
yet I boot with console=fb and if works ...
Sorry I re-read the code and I was wrong about a crash. The idea here was
to make console=fb fallback to the serial port (or whatever the default is
in the devicetree) if the framebuffer is not available.
Not sure off the top of my head how to solve this cleanly for non-simplefb
drivers, let me think about it...
