Yes, I've definitely used this on the NVIDIA Tegra Harmony board.

I tested the patch on top of repo u-boot-tegra.git branch master, but
the patch ended up getting applied directly by Wolfgang to u-boot.git. I
don't think that should cause any issues though; the patch shouldn't be
dependant on anything Tegra-specific.

I just re-tested to make sure. The exact code I tested is at:
git at github.com:swarren/u-boot.git mainline_dev

Do you have any clue why it's hanging or crashing? Perhaps you can add
some debug statements to see exactly where it's happening?
