onelife.real@gmail.com cabc797a2d *** EFM32 branch ***
1. Update the copyright information
 - 2009 => 2011
2. Add external oscillator configuration routine in "rt_hw_board_init()"
 - Before, it is set by default frequency, 32MHz
 - Now it can be set by user specified frequency
3. Add ADC and ACMP (analog comparator) drivers
4. Clarify the MCU and target board define in "rtconfig.py"
