I have found that "set tty fb0" is also necessary to get a console on the
Pinebook 1080P. I added this to /etc/boot.conf and can now get the framebuffer
console upon boot. This works on the final installed system, but I also had
success adding this to the install disk, which let me do the install without a
serial adapter. (If you time it right you can enter "set tty fb0" during boot,
but this can be difficult without any screen output.)

I don't yet have a patch to submit, but it looks like adding the generation of a
simple /etc/boot.conf to /distrib/arm64/ramdisk/install.md, inside
md_installboot(), may solve the post-install problem for the Pinebook. (Did you
have to add this on your Raspi system?) Note that the installer already runs
some vendor-specific steps for both Raspi and Pine, so this isn't unusual. I
imagine that this would work with other Pine boards, but I haven't tested it on
any of them, so I can't verify that.

Including a valid /etc/boot.conf with the ARM64 install image should also be
possible in theory, but I'm not sure if this would cause problems on other ARM64
boards, so this may not be as straightforward.
