for the sake of clarification, you write that i don't *need*
cuImages anymore, but that's not the same as saying that i *must* move
to using device trees. in fact, a cuImage file still works just fine
for my lite5200 boards, so obviously the version of u-boot that i've
flashed to my TQM boards can still handle that format.
so while it's probably a good idea to move to the device tree
recipe, that still doesn't explain why i can't use a cuImage file for
my tqm boards. so i'll test the device tree process later today, but
i'm still curious as to why a cuImage format file still fails in this
case when it works just fine for the other boards.
