This is the absolute position 'image-pos', as opposed to 'offset' which is relative to the containing section.

This can be overriden to adjust the contents of an entry in some way. For example, it would be possible to create an entry containing a hash of the contents of some other entries. At this stage the offset and size of entries should not be adjusted unless absolutely necessary, since it requires a repack (going back to PackEntries()). -11.

ResetForPack() - if the ProcessEntryContents() step failed, in that an entry has changed its size, then there is no alternative but to go back to step 5 and try again, repacking the entries with the updated size. ResetForPack() removes the fixed offset/size values added by binman, so that the packing can start from scratch. -12. WriteSymbols() - write the value of symbols into the U-Boot SPL binary. +11.
