How to call Trusty secure world application from inside linux kernel?

[eikansh]

I am trying to implement binary attestation from inside the linux kernel. The hash is calculated and needed to be send to secure world.

I have the trusty and kernel source provided by Nvidia. I am able to run the sample client and secure application. For the attestation task, I need to integrate the trusty client with the kernel.

Which files do I need to include in the linux kernel? What changes do I need to make in kernel makefiles to build trusty client with the kernel source code?
