Agree, I think majority of device-specific debugging was broken after 
ARM physical address length was changed to
64 bit. Of course, no one would want to run QEMU with ALL_DEBUG, but I 
think no one wants to configure QEMU with --target-list=all either, but
sometimes we have to)

But touching every device could be too invasive, maybe add new target to 
QEMU makefile "make compile-test", and ask for every new contributor to
manually add his debug define in some kind of list of defines for "make 
compile-test".
