I would prefer that we fix the u-boot port using 2019.07
I've never looked to what was the problem but if you have a board
could you test building after applying this patch to the u-boot source
tree :
diff --git a/scripts/Makefile.spl b/scripts/Makefile.spl
index 7af6b120b6..34e74506e3 100644

It might not work at all, I have no idea what cbs means for dd and
failed to understand with the man page.
