PC Engines apu coreboot Open Source Firmware v4.9.0.2

Key changes - Mainline
  • Enabled CPB feature.
  • Corrected AGESA headers, which were for newer AGESA version than used in coreboot.
  • Reproducible builds limitation - currently set iPXE and Memtest86+ master revisions do not guarantee the build reproducibility in long term. Correct revisions will be set in v4.9.0.3.
  • Performed an analysis of how to safely reboot the platform after firmware upgrade using available reset methods:
  • pcengines.github.io page has been updated with newsletter subscription option and a blog with release reports containing key changes, test statistics/charts etc.

Key changes - Legacy
  • Enabled CPB feature.
  • Reproducible builds limitation - currently set iPXE and Memtest86+ master revisions do not guarantee the build reproducibility in long term. Correct revisions will be set in v4.0.25.

Statistics
The chart shows the total files changed from release tag against the rebase point of given release specified in CHANGELOG (CHANGELOG.md and gitlab-ci.yml excluded from statistics). Check the statistics with:

git diff --stat <rebase_point_sha> ':(exclude)gitlab-ci.yml' ':(exclude)CHANGELOG.md'
The chart represents the total line added and deleted on the PC Engines coreboot fork against the rebase point for a given release. Check the statistics with:

git diff --stat <rebase_point_sha> ':(exclude)gitlab-ci.yml' ':(exclude)CHANGELOG.md'

Two files have not been included in the diff as mentioned above since they are not a part of coreboot tree. The difference has grown a little since some patches have not yet been merged and/or sent (AGESA headers).
