Very early WIP
Unlike x60 method, this one yields bricks at any step being performed wrong. Therefore script has to perform all the checks to make sure it's safe to reboot. It will also make situation far worse for WSON8 users, lacking skills to replace the chip, when bricked.
Which device is this? aka, which thinkpad model?
It's for X200/T400/T500. There also was a report on IRC of successful implementation (for internal coreboot flashing) on X201.
Hmm... I wonder if that means X201 will be librebooted soon... interesting. :o
