Can you explain how much the GH7 and Exynos front-ends actually have in
common? Would it make sense to have a separate driver for gh7?
Also, if gh7 is expected to run a full firmware, I think you should
do all the setup in the firmware before booting Linux, and just
do the required run-time operations in the driver itself.
