The Linux kernel configuration item CONFIG_TRUSTED_FOUNDATIONS
has multiple definitions:
drivers/firmware/Kconfig
The configuration item CONFIG_TRUSTED_FOUNDATIONS:
CONFIG_ARM && CONFIG_CPU_V7
Some devices (including most early 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 the functions and comments in linux/firmware/trusted_foundations.h or the device tree bindings for "tlm,trusted-foundations" for details on how to use it.
Choose N if you don't know what this is about.
arch/arm/firmware/Kconfig
The configuration item CONFIG_TRUSTED_FOUNDATIONS:
CONFIG_ARCH_SUPPORTS_TRUSTED_FOUNDATIONS
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.
