Coreboot-compatible Thinkpads

I've prepared a little cheat sheet of different coreboot/libreboot compatible Thinkpads along with instruction set, passmark score and if it's supported by Libreboot. I'm focusing only on 64-bit processors here. Hope it comes useful.

Disclaimer: Passmark score might vary due to more people attending the test after I posted this, don't treat these as absolute values.
