This is from a thread on the FreeBSD arm@ list.

I love the line about the plan to "gut GENERIC like a fish."  A cause
for optimism.

The current plan for 12 is that we'll gut GENERIC like a fish, at least on
x86, and ship with a more minimal kernel. Everything that can be loaded as
a module automatically will be loaded (there's some things that can't or
could be but with a crazy amount of work, those wills till be static). The
devmatch work I've done is driving it, but it isn't fully realized in
-current yet since there's lots of PCI drivers that need love.

For ARM specifically, we need a lot of work on the FDT side of the house to
get there, and there's some issues about the best place to do the loading
that might not be worked out by the branch for 12. Having a better story
for embedded is needed regardless of the progress towards automatic loading.
