Markus Hitter 137a638658 ARM: get timer.c in, so far only with the system clock. 
This test code in SysTickHanlder() should give you a rather
accurate clock with only a few seconds deviation per hour:

  #include "serial.h"
  #include "sersendf.h"
  void SysTick_Handler(void) {
    static uint32_t count = 0;
    static uint8_t minutes = 0, seconds = 0;

    count++;

    if ( ! (count % 500)) {   // A full second.
      seconds++;
      if ( ! (seconds % 60)) {
        seconds = 0;
        minutes++;
      }
      sersendf_P(PSTR("%su:"), minutes);
      if (seconds < 10)
        serial_writechar('0');
      sersendf_P(PSTR("%su\n"), seconds);
    }
  [...]

Markus Hitter feeb411eec ARM: split timer.c into platform specific files. 
AVR and simulator are kept together, because the simulator
apparently simulates much of the AVR timer infrastructure.

ARM variant is empty, so far.
