You did not nack it just said you'd prefer a header instead. As a reviwer 
you express your opinion not an absolute decision that can't be discussed. 
I've replied to that but could not drop this patch as it's needed for 
later patches to get mac.h cleaned so until we agree on something this has 
left unchanged. I'm not a fan of one line headers and splitting up files 
into separate directories that is harder to work with and also think 
reorganising grackle is a separate clean up out of scope for this series 
but OK, I'll move the TYPE define in a new header in the next version. 
I'll wait for your reply on sysbus_mmio_map before sending a new version.
