I really appreciate your proposal for a cleaner directory hierarchy.

Here are some more ideas:

* Move the target-xxx directories (currently 15) to target/xxx.

* Add host/xxx for host specific files (xxx = posix, wxx).
  Here the currently used win32 might be replaced by either
  wxx or by win as most of it also applies to w64.
  An alternative solution would add host specific subdirectories
  to include/qemu and util.

* Move machine implementations (code which calls machine_init)
  to the respective architecture directories (hw/arm, ...).
  Meanwhile we have more than 50 machine implementations in hw.
  We could also replace hw/alpha, hw/arm, hw/cris, ... to
  hw/arch/alpha and so on.

* Move hardware implementations which are architecture specific
  to the architecture directories. This is sometimes less obvious
  than the machine implementations.
