Coreboot or proprietary BIOS?

Has a decision been made regarding the BIOS?

It seems that uboot will be used, thus the bootloader is free (GPLv2): https://gitlab.labs.nic.cz/turris/turris-omnia-uboot
I don’t know if blobs are needed to boot.

Thanks, I’ve also read an official answer made in another thread where it’s mentioned that it’s unlocked and writeable.
