        Sets the image size in bytes, for example 'size = <0x100000>' for a
        1MB image.
 
+offset:
+       This is similar to 'offset' in entries, setting the offset of a section
+       within the image or section containing it. The first byte of the section
+       is normally at offset 0. If 'offset' is not provided, binman sets it to
+       the end of the previous region, or the start of the image's entry area
+       (normally 0) if there is no previous region.
+
 align-size:
        This sets the alignment of the image size. For example, to ensure
        that the image ends on a 512-byte boundary, use 'align-size = <512>'.
