Seems simple enough it doesn't really need many, but for Tegra,
Acked-by: Stephen Warren <swarren@...dia.com>

Which kernel is this going into? It's possible Tegra will get converted
to multi-platform in 3.10, which might move that main ARCH_TEGRA block
from arch/arm/Kconfig into arch/arm/mach-tegra/Kconfig, although I
suppose it doesn't /have/ to move it. I think some/all(?) other
multi-platform conversions have moved their main Kconfig option like
that though.
