Not currently but I'm working to have that work for Fedora 29. Basically at the moment it uses a kernel provided DT which is loaded and passed to the kernel by U-Boot. My plan for F-29 (I was hoping it would actually be in F-28 but there was issues and I don't have the time to finish it) is to use the firmware to load a "upstream kernel" DT which then uses the dtoverlay configurations bits in config.txt which the RPi firmware mashes them all together as a single DT and passes it to U-Boot which in turn passes it onto the kernel enabling us to use support HATs. I believe all the bits are now in place (firmware, U-Boot etc) and I just need to apply some config and test to make sure it all works, and falls back to the current way if there's not bits specified.
