I rewrote nvmutils. The new project is "nvmutil", building one binary.

It can set MAC addresses (e.g. on X230), fix(or break) checksums, swap parts and dump info about PHY NVM files for Intel GbE NICs.

The code is much cleaner: https://notabug.org/osboot/nvmutil

I wrote nvmutils back in February, to make changing MAC addresses on ThinkPad X230 coreboot ROMs easier. I automate it, when setting up customer laptop.

Works on T440p too, and lots more e.g. Libreboot X200 (and not just ThinkPads either).
