The old imx6 uboot ports generated a single copy of uboot that would
boot dual and quad-core versions of both hummingboard and cubox
systems.  If the new uboot works only on quad core, that's another
regression.  It might be possible to extract the u-boot.imx file from a
freebsd 10 image to get back to the old one.

Ooops.  Except it appears those no longer exist.
