Thanks Jan,
actually mem=3840M is the only thing required to get the demo running.
device tree and CMA=32M reservations do not bring anything visible.
I haven't fully investigated but I'll do.
Maybe also that hint in the config was blindly copy&pasted from another
one - wouldn't be the first time. Sorry in that case.

I don't have that board in reach to check how reservation looks like in
the good case, but you can get an image that is supposed to work from
jailhouse-images. Or pick up patterns from there, like the reservation
via "mem=3840M" [1]. Maybe start you system with that setting and
compare the reservations.
