One of the qdev intended benefits is to have pretty much self-contained
device emulation. If doesn't work equally well everythere. For alot of
-- for example -- PCI devices it does work nicely though. Adding a
device is simply a matter of dropping a file into the tree and a line
into the Makefile and you are done. The device is available to be used
via -device. So the cost of maintaining stuff out-of-tree isn't that
big as you almost never have patch conflict issues.
For embedded stuff it is usually a bit trickier as the device
interconnects are hard-coded in the board creation bits and devices
can't be hooked up using -device (or some other generic mechanism which
uses -- say -- device trees) ...
cheers,
Gerd
