Right, it uses USE_OF by default because the TEGRA_DT board was
enabled. The defconfig should really be a superset of needed configs
for running on most hardware out there (since we do a multiplatform
kernel), so keeping it enabled on Tegra does make some sense.
Also, the direction is to keep moving towards 100% device-tree (on
tegra), it does make sense to keep it enabled. For testing, explicitly
disabling it to compile-test will be needed for a while longer, but I
don't expect to do much !USE_OF work (for tegra specifically) in the
times ahead.
When changing ARM-generic core code, you should probably pick a few
other defconfigs and make sure those build as well -- that should
cover those aspects.
