-Title: Boot Time Measurement
-
-Description:
-
-BootTime measures the time:
-   a) from system reset to kernel start (crt0.s's __start)
-   b) from kernel start to begin of main()
-   c) from kernel start to begin of first task
-   d) from kernel start to when kernel's main task goes immediately idle
-
-The project can be built using one of the following three configurations:
-
-best
--------
- - Disables most features
- - Provides best case boot measurement
-
-default
--------
- - Default configuration options
- - Provides typical boot measurement
-
-worst
--------
- - Enables most features.
- - Provides worst case boot measurement
-
---------------------------------------------------------------------------------
-
-Building and Running Project:
-
-This benchmark outputs to the console.  It can be built and executed
-on QEMU as follows:
-
-    make run
-
---------------------------------------------------------------------------------
-
-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
-
---------------------------------------------------------------------------------

-Sample Output:
-
-tc_start() - Boot Time Measurement
-Boot Result: Clock Frequency: 25 MHz
-__start       : 88410717 cycles, 3536428 us
-_start->main(): 2422894 cycles, 96915 us
-_start->task  : 2450930 cycles, 98037 us
-_start->idle  : 37503993 cycles, 1500159 us
-Boot Time Measurement finished
-===================================================================
-PASS - main.
