Hi All,

The buildsystem of TF-A became complex and loaded with technical debt during the years, and it's time to do something about this. We made some plans and prototyping work to move to a CMake based solution and we would like to get feedback on the idea.

Why CMake? In summary CMake is a mature tool having a wide acceptance in C and C++ projects. Also it has benefits of decreasing fragmentation in the developer community if we sync up with TF-M.

How will it happen? This will be a slow process where the old build system will co-exist for a period with the new one. How long that period will be is an open question.

For a more detailed summary please see https://developer.trustedfirmware.org/w/tf_a/cmake-buildsystem-proposal/

The design discussion will follow the design review proposal process of TF.org, as described on this page: https://ci.trustedfirmware.org/job/tf-m-build-test-nightly/lastSuccessfulBui...

You can find the patch for capturing the design decisions and discussion here: https://review.trustedfirmware.org/#/c/TF-A/trusted-firmware-a/+/2662/
