Anyway, will be nice to have a comment here as it is not only parsing the firmware, you collect some information like copy of the resource table, list of elf segment to dump... I think it is important to be clear about resource table management as it is a key element of the remoteproc core, where it is loaded, where it is copied back in memory...
