I've only moved vars to the new machine state that will be needed outside 
of the init method for VOF and rom isn't so that's kept local. It could be 
put there for consistency but not really needed so I've left it here.

Thanks. By the way, even though this series allows loading Linux and 
MorphOS without the board ROM I'd prefer to keep the test using the ROM as 
implemented in your series because that excercies the emulation more than 
booting without ROM as the firmware inits more devices and uses more 
facilities that VOF mostly bypasses so for a test the board firmware is 
more complete.
