This is ofcourse a half baked implementation and only limited to reloading uC firmwares. This needs to be extended for a lot of different components which I've skipped here for my lack of competence, so feel free to join in and support them. PS: This works enough to allow a single exec test run after FLR but it follows with a GuC crash on subsequent runs which I'm still investigating.
