cbfstool is a part of coreboot, used for modifying the filesystems of coreboot rom files.
Here is an OpenBSD port. One patch was necessary to remove a flag in the makefile which caused building it to fail. Tested on amd64, probably works on x86 aswell but have not tested it. I do not wish to maintain this, the program is very simple and should be easy to keep functional with updates. Best regards, cat
