Yonattan Louise dbada63eee Fix coding style issues. Some checkpatch issues were solved by scripts leaving other problems such as alignment and indentation issues. In order to comply with the defined coding style the following fixes were made: - Fixed the function declaration moving the parameters' comments above the function in accordance to the doxygen format. - Fixed functions' opening and closing brackets. These brackets should not be indented. - Fixed the 'if', 'for' and 'while' statements adding the brackets around the sentence. - Fixed comments' alignment. - Fixed indentation. The work was done manually and submitted as one commit. I didn't separate these changes in different commits because they were fixed all at once. Basically, all errors were fixed in every file at once.

Title:  BootTime

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 microkernel'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 microkernel project outputs to the console.  It can be built and executed
on QEMU in three possibile configurations as follows:

    make pristine
    make BOOTTIME_QUALIFIER=best microkernel.qemu

    make pristine
    make BOOTTIME_QUALIFIER=default microkernel.qemu

    make pristine
    make BOOTTIME_QUALIFIER=worst microkernel.qemu

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

Sample Output:

tc_start() - Boot Time Measurement
MicroKernel Boot Result: Clock Frequency: 20 MHz
__start       : 377787 cycles, 18889 us
_start->main(): 3915 cycles, 195 us
_start->task  : 5898 cycles, 294 us
_start->idle  : 6399 cycles, 319 us
Boot Time Measurement finished
