The tinyos-msp430 should be able to combine any oscillator and any timer that the chip has to provide as a source of tinyos standard timer module.

Now, the timer and oscillator configuration are pretty much hard coded in the source. Those code should be reconstructed as:

• The chip code (under tos/chips/msp430-small/msp430*) "provides" all timers and oscillators that the chip has.
• The platform code (under tos/platforms) can "uses" any oscillator and timer the chip provides and combine to "provides" as a source of tinyos standard timer, such as HilTimerMilliC or Msp430TimerMicroC.
