Heh that's annoying. The original branch I forked that Laurent was working on 
had
some extra patches at the start of the series: some were required for q800 
whilst
others were for new development. I thought that all of the patches required for 
q800
had been applied over the past few months, but sadly that isn't the case :(

I've pushed an updated branch to https://github.com/mcayland/qemu/tree/q800-test
which contains the patchset plus two extra patches that are still needed to 
boot to
the debian installer here:

9281a5371f "tmp"
629754d847 "target/m68k: manage FPU exceptions"

Laurent, are these patches ready for upstream or do they need work in which 
case we
should leave q800 until the 3.2 cycle?


ATB,

Mark.
