Flashing chip with Lime 2

[ElVirolo]

Hello everyone!

I'd like to flash coreboot on a Lenovo Thinkpad x220 BIOS chip. This guide describes the steps needed to do it using a Raspberry Pi. A friendly person on #olimex@freenode.net told me, succinctly, how do to it with my Lime 2 board, but I'm a bit lost.

I'm thinking of buying this SOIC test clip as well as A20-OLinuXino-LIME2-UEXT and  CABLE-40-40-10CM, which I would hook up to these 0.1" F2F jumper cables.

1) Are the aforementioned pieces of hardware suitable?
2) Which GPIO pins exactly should I be using?

Thank you very much for your help,
