I'm dealing with a backlog of orders. Will send email updates soon. Reckon I'll be caught up next week.
Sorry for the delay in your order. I'm putting this here as well as email. I took on too many orders during and after moving my office recently. Shipping as fast as I can.
FUN FACT: I added edk2 payload to Libreboot (MrChromebox's edk2 fork for coreboot). This is a highly advanced UEFI payload. EDK2 is Intel's project, and it's open source; it's the reference implementation. Check recent commits for edk-related config:

I'm shipping edk2 on next week's orders. edk2 is default now. It's like I said on IRC: GRUB and SeaBIOS are now legacy. I'll still maintain these, but edk2 is now the preferred payload.
It's... UEFI. I booted Arch Linux earlier with UKI. Much easier to use than GRUB.
Tested on sandy/ivybridge, broadwell, haswell, kabylake.
This will be in next Libreboot release.
So... you can use e.g. systemd-boot, and BSDs are easier too. Linux distros are generally easier. It works like normal firmware (but it's Libreboot).
EDK2 integration is only part of a general effort to modernise Libreboot. You can find the upstream here: https://docs.mrchromebox.tech/ - Libreboot has integrated the EDK2 part of this project.
Matt (mrchromebox) has been helping me. He maintains this payload for Chromebooks but it works on other boards.
A lot of people don't know but pretty much every major computer vendor you buy from will ship with a variant of EDK2, though they ship proprietary forks. MrChromebox is an open source version, made specifically to boot as a coreboot payload. Matt maintains it for Chromebooks so that you can run normal Linux distros on those devices, and it offers a lot of really nice features.
It's a huge project. Matt has been doing it for years. I'm planning to add his Chromebooks to Libreboot as well, at a later time, working with MrChromebox when I can.
