I've been working on trying to get a mainline or nearly mainline kernel
working for pinebook pro, and there's a little better support in
linux-libre 5.5.

According to:

  https://linux-libre.fsfla.org/pub/linux-libre/releases/

The 5.5 patches have been available since late January, and seem to be
getting regular updates as needed.

So far, I haven't had time to test and update linux-libre 5.5 with the
kernel configs and so on, so I've been working on a
linux-libre-arm64-generic package that uses the defconfig (much like
linux-libre-arm-generic) and linux-libre 5.5.x.

5.4 is a long term support kernel, so I guess that would likely stick
around regardless.  5.6 is probably going to come out soon, so wondering
if it's worth updating to 5.5.x?

Any issues with pushing a linux-libre-arm64-generic package to master
based on 5.5.x?

The following patches add linux-libre 5.5.9 (leaving the default at
5.4), linux-libre-arm64-generic, and adds a patch from linux-next to
enable limited support for pinebook-pro. Once I've tested 5.5.10, i'd
probably end up pushing that.
