[coreboot] Mac Book Air 2019 firmware update

[Ivan Cubillas Castellanos]

Hi everyone,

Thank you in advance for your attention and I am sorry for my low english
level, I am Spanish.

I have a doubt because a friend give me as a gift a 2019 macbook air with
an I5 Amber Lake processor. This Macbook Air has an Activation Lock with an
unknown apple ID, I think that an interesting option could be change this
OS for an Ubuntu version, I can boot Mac Book Air in DFU mode, but I am not
sure if I coreboot option will be possible and how I can compile or install
it, in order to substitute mac os recovery mode. Is it possible?

Thank you very much in advance for reading my question, Regards Ivan.
