I noticed that the Jetson TK1 hangs during boot (when/before mounting

The hang does not occur when I disable tegra-devfreq or when I use
tegra-devfreq in combination with u-boot 2016.03 (from DENX upstream,
built by Debian).
Steps to reproduce:
ARCH=arm make multi_v7_defconfig
Set CONFIG_ARM_TEGRA_DEVFREQ=y
Boot from an external SD card and it will hang when/before mounting the
SD card.
Stephen, any ideas what might be going on here?
I can't think of anything obvious, and the commit history of the L4T
U-Boot is constructed in such a way that's it's essentially impossible
to follow, so I can't easily tell what changes exist in the L4T U-Boot
release that weren't upstream or vice-versa. If simply using mainline
U-Boot works and is an option for you, I'd suggest that.
