Anas Nashif 10bb38c186 Use SoC instead of platform. Change terminology and use SoC instead of platform. An SoC provides features and default configurations available with an SoC. A board implements the SoC and adds more features and IP block specific to the board to extend the SoC functionality such as sensors and debugging features.

Title: Kernel Event Logger Sample

Description:

This sample uses the philosopher sample with two additional tasks to show the
profiling data on different system's states. The fork manager task controls the
fork's availibilty. The worker task performs intermitently heavy processing,
allowing or preventing the system to go idle.

Building and Running Project:

This microkernel project outputs to the console. It can be built and executed
on QEMU as follows:

    make qemu

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info
