Also if you use ints on real bus as description, you may want to clarify restrictions on mmio.len. Basically on 32 bit platform (i.e like V7 ARM) one cannot have mmio.len=8, because one cannot have 64bit value on 32bit data bus. Without such clarification introduction of text like "the value as it would go on the bus in real hardware" is confusing for len=8 for emulated CPUs where real busses are 32bit.
This is not necessarily true. On a 32-bit CPU you can have a 64-bit memory bus. Even x86 32-bit CPUs can do 64-bit MMIO via MMX or SSE or double-word compare-and-swap (CMPXCHG8B).
