I was advised to regenerate the kernel configs using "make oldconfig",
but there was nothing obvious *to me* to change, and I ended up hitting
enter the whole way through... so leaving with these for now.

The pinebook pro portions have already been merged for 5.4.x, and still
apply to 5.5.x.

Attached is the first patch of an updated series for linux-libre 5.5.13,
following up with a second patch to actually switch the default to
5.5.x.  Boot tested on x86_64.

I'm tempted to at least merge the first patch and create a
linux-libre-arm64-generic-5.5 package until it switches to the
default...


live well,
