Building Nouveau driver (CONFIG_DRM_NOUVEAU) fails on branch patches-l4t-r32.2.1:

I doubt NVIDIA does any testing with this kernel for any configuration outside of what they support in their L4T BSP, so I'm not surprised that nouveau doesn't build. Upstream should have some support for nouveau on at least some of the Tegra SoCs.
