Hi,
Just a note that the U-Boot / vboot integration has been updated with the 2018 version of vboot and it makes full use of driver model.
If it available at [1]
Documentation for running it on coral (2018 Intel Apollo Lake Chromebook) is available [2] as well as running it on sandbox [3].
The earlier release for 2015's samus (Chromebook Pixel 2) and 2012's link is still available at [4].
As a further note, the new cros-2021.04 release is now available [5].
This improves the coral support slightly and adds the ability to boot verified boot on top of coreboot (for coral only at present). It also includes updated documentation with 'make htmldocs'. The base implementation is in a cros/ subdirectory and consists of 15K LOC including documentation and devicetree files. You might find the talks at [6] useful.
It is built on top of the just-released U-Boot v2021.04.
Future work will update the implementation to 2021 vboot (currently it is using 2018), but this may involve moving to a newer board, since Coral was released with 2017 vboot. The differences are mostly refactoring.
Regards, Simon
