ta/Makefiles: Set LDFLAGS to null before building ta make scripts

Yocto can set LDFLAGS to values that are incompatible with building a TA.
This patch ensures the LDFLAGS from the environment is unset prior to
calling make for a TAs Makefile. LDFLAGS settings for the host binaries are
unaffected meaning that yocto can set LDFLAGS to whatever is standard for
user-space w/r to the host binaries but, the TA devkit LDFLAG settings will
be used for TAs.

OP-TEE Sample Applications

  3. How to build a Trusted Application

1. Introduction

This document describes the sample applications that are included in the OP-TEE, that aim to showcase specific functionality and use case.

For sake of simplicity, all OP-TEE example test application are prefixed with optee_example_.

2. List of sample applications

Directory hello_world/:

  • A very simple Trusted Application to answer a hello command and incrementing an integer value.
  • Test application: optee_example_hello_world
  • Trusted application UUID: 8aaaf200-2450-11e4-abe2-0002a5d5c51b

Directory random/:

  • Generates a random UUID using capabilities of TEE API (TEE_GenerateRandom()).
  • Test application: optee_example_random
  • Trusted application UUID: b6c53aba-9669-4668-a7f2-205629d00f86

Directory aes/:

  • Runs an AES encryption and decryption from a TA using the GPD TEE Internal Core API. Non secure test application provides the key, initial vector and ciphered data.
  • Test application: optee_example_aes
  • Trusted application UUID: 5dbac793-f574-4871-8ad3-04331ec17f24

3. How to build a Trusted Application

TA basics documentation presents the basics for implementing and building an OP-TEE trusted application.

One can also refer to the examples provided: source files and make scripts.
