Libreboot: Can I make ROMs on a powerful computer and then flash using RspberryPi

I will be trying to flash LibreBoot (a particular coreboot downstream) on to a thinkpad T440p. Even with libreboot - instructions are quite complex, but look entirely doable. There is one thing, however - I cannot be sure if I can make the boot roms using lbmk on a relatively powerful linux computer (running manjaro/arch) and then flash using RaspberryPi, or must I make the roms on the raspberrypi that I will be using for flashing (with a SOIC-8 clip). Intuitively I think there should be no problem, but I just don't know this area. Perhaps someone who understands this better, or who has done libreboot flashing could explain this?
