postmarketOS supports 4 Chromebook devices
Rockchip 3288 and Exynos 5420 chips
They were first released 20011 and 2014. So they are old!!!

Also I noticed someone is doing support work on
"Apple Macbook Air M1 (apple-MacBookAir10,1)"
This device does currently boot and works to a degree, it has a actively developed Linux port (https://asahilinux.org/), as well as a somewhat working port by corellium that is claimed to be "completely usable" yet lacks any optimisation
