Thanks, Jon.  That makes the new u-boot "fdt" command tremendously 
easier to use because you can now allocate extra space in the blob at 
compile time rather than having to reallocate space using the u-boot 
"fdt" command.

Note to u-boot "fdt" command users:
* Pull the latest dtc source from Jon's repo
     <http://www.jdl.com/git_repos/>
* When you compile your dts, use the new -S parameter to create some
     extra space (e.g. -S 0x2000).  If you don't want to guess how big
     your current blob is, run a test compile with -S 1 - you will get
     a warning (don't use -q ;-) that will tell you how big your
     blob is.  Re-run with a reasonable -S.
* The -R to make extra mem reserve slots may be useful too.
* Make sure you *don't* specify version 16 (some legacy recipes do
     that).  The latest version is 17 and dtc now Does The Right Thing
     without needing the version specified.  Do *not* use -V.
