Well, for what it's worth a kernel driver has been submitted upstream and is
queued for the 5.1 merge window:

https://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git/commit/?h=for-next&id=9b7e6242ee4efcd7f9ef699bf1965e3a5343f216

The patch does say it needs bootloader support though, and I'm not exactly
sure what that involves. I've added Stefan to Cc, maybe he can provide some
insight.
