Hi Russell,

* You need to use version 17 (simply don't specify -V 0x10).
* As Kim mentioned, you need -S padding to allow extra space for the
     /chosen node.
* Since you burned the blob into flash, bootm has to relocate the blob
    to RAM.  This is what is giving you the "fdt move failed" error in
    your first example, it is moving the blob to 0x007fe000 - is this
    a valid address (seems like it should be)?  Perhaps it is simply
    because you didn't pad it?  Perhaps we let a bug slip in?

Good luck,
