Hi Stephen,
I checked out the latest code and try flashing on DM355 for NAND boot mode, I saw that saveenv was causing a hang. A little debugging pointed me to this patch http://patchwork.ozlabs.org/patch/174069/ reverting this patch saveenv works fine. Has this patch being tested ? Or is that I am missing out some where.
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@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?
I added some debug statements and saw that in hexport_r() function where memset(res, '\0', size); is done this where it hangs :(. hope this might help.
For the list archives: I believe the following patch should fix this:

Sorry for the breakage.
