[U-Boot] u-boot-dm crashes on NVIDIA Jetson TX1 running "version"

[Stephen Warren]

Simon,

With the latest code in u-boot-dm.git/master, the "version" command
crashes on p2371-2180 (NVIDIA Jetson TX1); see log below. Preliminary
results show complete failure on Beaver and Jetson TK1 (the tests are
running so I can't see the full logs yet, but every py.test test that's
completed so far results in an error, so perhaps the same issue or
perhaps something else)
