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
Note to u-boot "fdt" command users:
* Pull the latest dtc source from Jon's repo
* 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.
