- * ======== UTIL_Wait ========
- * Purpose:
- * This fucntion busy waits given a certain number of micro seconds
- * independent of the processor speed. This is acheived by the
- * OEM functions QueryPerformanceCounter and QueryPerformanceFrequency.
- * Parameters:
- * u32 Number of Micro seconds to busy wait
- * Returns:
- * Nothing
- * Requires:
- * UTIL_Initalized.
- * Ensures:
- * Busy waits x Micro seconds or Sleeps X milli seconds; in that
- * case, it is a blocking call there will be a context switching
- * hence it may not represent the absolute busy wait time.

Wrappers only hurt readability, use native kernel functions instead (udelay, mdelay). Also remove useless defines.
