Having to modify every machine type seems to me like a huge red flag that this
is the wrong approach for device level tests. Surely the right thing is to
(a) instantiate the device (b) manipulate it via its publicly exposed interfaces
(ie the memory regions, gpio signals, irqs, etc etc) ?

Alternatively if you're just testing features of the device as it
is wired up on the board then you want something that generates an
image that can just be run on the unmodified QEMU model; that then
lets you cross check by running your tests on real hardware.
