2. Added apu6 platform support.

Statistics

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

git diff --stat da3375e ':(exclude).gitlab-ci.yml' ':(exclude)CHANGELOG.md' ':(exclude).gitlab-ci/regression.sh'

108 files changed, 4213 insertions(+), 451 deletions(-)

The chart represents the total line added and deleted on the PC Engines coreboot fork against the rebase point for a given release.

Three files have not been included in the diff as mentioned above since they are not a part of coreboot tree.

Testing

• PC Engines hardware configuration matrix - hardware configurations available for testing in 3mdeb laboratory.

• PC Engines release validation results - please note there are separate sheets for each board-release.

• Mainline:
  • PASSED: 617 (+75)
  • FAILED: 7 (+1)
  • PASSED [%]: 98.89 (-0.04%)

Key Changes in testing

1. Added manual tests results of apu6a (which significantly increased the total number of tests).

2. There were changes to SD card device tests to handle SD expander modules properly.

3. There were added small corrections to handle ECC with more precision.

4. OS Preseeds have been differed between the platforms.

5. There has been added a config for 10 pin TPM as a module.

What we planned

1. Improve the support of TPM2 in coreboot and SeaBIOS. Currently there is only the TCPA (TPM1.2) log support in coreboot. Additionally SeaBIOS overwrites existing entries in TPM2 log area. cbmem utility also lacks support for displaying TPM2 log area.

   WORK IN PROGRESS

2. Reorganize runtime configuration by making it persistent across updates and accessible from user space. Also prepare a tool for offline binary modification.

   VERIFICATION

3. Vital Product Data (VPD) support. User will have possibility to store and change VPD configuration in Read-Write section of SPI flash. Moreover, default VPD keys and values will be stored in Read-Only region to protect data against corruption. Also, sortbootorder runtime configuration will be stored in VPD Read-Write section, so access to it will be possible in OS via dedicated util.
