Thanks for this.  I've actually been working on new stages and a new
netboot, but very slowly, as I haven't had much time available.  I'm hoping
to put something out after the US Memorial Day holiday after I can build new
kernels (4.18.20) with the current netboot image.  The stages themselves are
based off of a 20190323 portage snapshot (it takes about 2 months to fully
build complete stages for six different targets).  Userland is based on
gcc-8.3.0, binutils-2.32, and glibc-2.29.  I have a uclibc-ng target
(MIPS-II, o32) as well.

Porting work to kernel 4.19 has been started and is mostly complete, except
the recent DMA API changes are still a blocker.  There's been renewed
upstream activity on fixing the SGI IP27 (Onyx/Origin) machines, from which
IP30 is related, so that will probably further slow down new kernels until
the dust settles.

I am also working on building up a musl target (MIPS-III, o32), but this
will take awhile as I have to start from scratch on that (currently piecing
together a seed stage for catalyst).
