Thanks for the note. We thought that mfw_isink was completely broken
on i.MX6.

There is absolutely no difference in this area (IPU) between the
SABRE Lite board and Nitrogen6X. I suspect that those with SABRE SD
boards can also confirm that mfw_isink fails in the same way with the
default compilation.

We noticed it in LTIB builds.
