in repository device-tree-compiler.

commit 7ea144f4c0b47c6f25cb4862b3299b7e5d7f7813
Author: Jerry Van Baren <gvb.uboot at gmail.com>

    Fix the -S to modify the totalsize properly.
    
    With the last improvement to pad out the blob, I broke the blob
    header totalsize adjustment.  The adjustment was moved up in the
    code before the memory image of the blob is created.
