As discussed previously (https://lkml.org/lkml/2013/11/26/289), enable Trusted Foundation support by default since it already depends on a supporting architecture being selected.

Some devices (including most Tegra-based consumer devices on the
|
|
market) are booted with the Trusted Foundations secure monitor
|
|
active, requiring some core operations to be performed by the secure
|
|
monitor instead of the kernel.
|
|
|
|
This option allows the kernel to invoke the secure monitor whenever
|
|
required on devices using Trusted Foundations. See
|
|
arch/arm/include/asm/trusted_foundations.h or the
|
|
tlm,trusted-foundations device tree binding documentation for details
|
|
on how to use it.

Say n if you don't know what this is about.
