coreboot changelog Jan 20 – Jan 26

This changelog covers 111 commits in the week between January 20, 2016 and January 26, 2016. (aad9b6a – 7ee6cd5)

There was another large set of patches continuing the work that has been done extending cbfs and integrating FMAP.  This series is expected to be finished in just a few more patches.

This past week saw the addition of two new mainboards – the Google Tidus board (Lenovo ThinkCentre Chromebox), and the Purism Librem 13 laptop.  Updates to the Google Oak board and its associated SoC, the Mediatek MT8173 Cortex A72, accounted for roughly 20% of this week’s changes.

The AMD native memory initialization for the family10h/family15h chips had more changes, with still more coming next week.  On the Intel side, the Pineview northbridge saw a couple of updates, and there were several fixes for for Intel’s Braswell and Skylake chips.

coreboot also had some more toolchain updates this week, adding an ada compiler for some upcoming work, and getting the gcc build set up for the Power8 work.  There were also a couple of fixes for building tools under NetBSD

In the coming week, we should get the 4.3 release finished, and see a slew of changes as the patches that are currently in review get merged.

coreboot changelog Jan 5 – Jan 19

This changelog covers the 180 commits between January 5, 2016 and
January 19, 2016.  (af91b8b0 – 967881d0)

We’re preparing for the coreboot 4.3 release, expected to happen sometime in the next week, so there has been a lot of activity surrounding Intel’s Skylake chips, both in the mainboards and SOC directories. The Skylake and braswell platforms are finally being build-tested by jenkins, which will help keep the platforms working.

The changes in cbfstool are continuing to roll in, although this should be wrapping up before long as the merger of cbfs with FMAP is completed.

The effort to standardize coreboot’s license headers across all files is just starting, and will be going on for a few weeks as we verify that all source files have the correct headers.  We’ve added and improved the lint checkers for these so expect failures from jenkins if files with non-compliant headers are pushed.

A fair amount of work was done in the build system in the past couple of weeks.  This removed the warnings about cross compilers not existing unless that architecture is currently being built, fixed some dependency issues, and fixed several other minor issues. A make target to check the versions of the coreboot toolchain was also added.

We had a slight toolchain change, going to MPFR version 3.1.3 to fix some issues seen on the upcoming Power8 processor.

Additional changes added NetBSD support for various utilities, and update the intel/gm45 and intel/pineview northbridges.
