ben-wpan/atusb/fw/atusb.c
Werner Almesberger 8c57277953 atusb/fw/: added free-running 48 bit 8 MHz counter for clock measurements
- atusb.c (main): poll the 16 bit timer for overflows
- board.h (timer_poll, timer_read), (board.c (timer_h, timer_poll,
  timer_read, board_init): added support for a free-running 48 bit timer
  (16 bits in hardware, 32 bits in software)
- include/atusb/ep0.h (ATUSB_TIMER), ep0.c (my_setup): new request
  ATUSB_TIMER to retrieve the value of the 8 MHz counter
- include/atusb/ep0.h (enum atspi_requests): describe what the groups
  of requests do
