Cool!

Does upstream know about it?

??? How can that be?  Isn't it required for booting?

I checked the source code - apparently they use mkimage
to build the itb from the its.  So now we are using two
"different" mkimage tools.  OK I guess - but weird.

All they'd have to do is add 

 ALL-y += u-boot.itb

to the Makefile.  Does upstream know about it?

Please use "invoke". It's shorthand for (zero? (system* ...)) but it also
raises an exception on error.
That's easier to maintain (when people add a second invocation they
don't have to add "(and ...)").

So here it would be (apply invoke "make" `(,@make-flags ,"u-boot.itb")))) .

Please end this phase with "#t".

>+      (version (string-append "1.3-" revision "." (string-take commit 7)))

Please use (git-version "1.3" revision commit) instead of 

(string-append "1.3-" revision "." (string-take commit 7))

Sometimes the indentation you used is slightly off, like this:

  `((foo)
   (bar))

It should be

  `((foo)
    (bar))
