Hello Carl-Daniel, I did one round of timing the build processes:
Original make command: 0m42.323s My reduction and a clean start: 0m30.955s After that a 'make clean' and renewed make: 0m23.081s The timings might not be typical, but the time saving seems to be substantial in the 'middle case' where only one romcc needs to be built, as well as in the last case were romcc is fully reused for both rom-images. Since I only have used coreboot-v2, I have no knowledge whether my utility could be applied also to coreboot-v3.
