I did not got hands on framework till now, its neither in my country nor my parents (I’m a student) can afford it until my current laptop goes out completely, but I’m sure my next laptop is going to be 100% framework…
The officials have confirmed that the EC is exposed, and I’d guess it should work without any problem on framework.
As pointed out, it is based on chromium-ec which was probably used in old lenovo thinkpads as well (zephyr framework appeared in 2016), even if sources might be different it would be easy to integrate as can take inspiration from old tlp sources and adjust accordingly for framework.
Add a new forum page if it does not work, implementation should be quick, unfortunately can’t test it out from my side :^(
