Hi Peter- I actually had NOT come across mkelfimage! It may have to do with the fact that this page appears to be a stub:
https://www.coreboot.org/Mkelfimage and searching on the new documentation site yields no hits. Interestingly, the Google result for that page does show some text. Maybe an old version has it? I'll investigate. Thanks for the hints so far, either way! R Peter Stuge <pe...@stuge.se> schrieb am Fr., 19.
