Hello Vlad!
First of all, thank you very much for porting Coreboot to the X230.
I'm following your instructions [1] to build a coreboot image from head, but I'm not sure how to configure things in menuconfig. Would you mind sharing your .config file and a prebuilt, known-good rom file?
Also, while I'm waiting for the SOIC test clip to ship: do you know if anyone is working on getting flashrom to work with the X230?
