I have one more patch to send Tim so that crochet always builds u-boot from release v2014.4 because the latest release (v2015.1) broke some things which will require other tweaks to crochet.

We should just turn your u-boot changes into a port.  (Hmm, wasn't there
a licensing question on one of the files it needs, though?)

Once a u-boot port exists, there should be minimal "trouble" in creating
an image for it.  We are very close to having an armv6[hf] world which
doesn't need UBLDR_LOADADDR set, which means a single world can be used
to poplulate all the various images.  The only thing that will differ
per-image is the kernel (and related dtb files) to install, and which
u-boot package to install.  So there will be a little bit of config for
Glen to set up for each supported board, but each added board won't
require its own complete buildworld.
