Re:How is the free firmware for the Raspberry progressing?

lk-overlay contains many different projects
using the vc4-stage1, vc4-stage2, and rpi2-test projects together, you can do the entire boot chain (dram init and loading linux) using open source code
other projects act as demo's or tests on how to run custom code at various stages, but not actually boot linux on the arm core many of those demos work on the the entire pi model range
pi3 support is only broken due to arm side problems, which could be fixed by just using a different bootloader
and the https://github.com/librerpi/rpi-open-firmware codebase can already boot linux headlessly on both pi2 and pi3, it uses a different arm bootloader
(Albeit, currently only on a Pi 2)
EDIT: Actually, reading more carefully it looks like there might be more than one blob and it's not 100% clear to me which this replaces, so now I'm less sure.
