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" git-svn-id: https://rt-thread.googlecode.com/svn/trunk@1296 bbd45198-f89e-11dd-88c7-29a3b14d5316
