How is the EC firmware in this repostory related to FrameworkComputer/zephyr?

[HuggeK]

Is FrameworkComputer/zephyr the future of EC firmware on new products?

[DHowett]

Zephyr is a real-time operating system. It is also the operating system the EC firmware is built on top of¹. It does not replace the code in this repository; it is required by it.

The explanation by @DHowett is correct.

Our EC firmware has been based on Zephyr since 2023, starting with our AMD laptops and everything since then.

For example see:

EmbeddedController/.github/workflows/zephyr-build.yml

Line 54 in 01e6abe

pushd src/third_party/zephyr/main

During the build we pull in zephyr as a dependency.
