Hi Frederic,

I've now had a chance to review this - I think it basically looks good, it just 
needs
a few minor tweaks. I can also confirm that using the test images at the URL 
above, I
can boot to a userspace shell.

I'm happy to take this through my qemu-sparc branch once everything is ready to 
go.


ATB,

Mark.
