ben-wpan/atusb/fw/include/atusb/ep0.h
Werner Almesberger 9a0184cacb atusb/fw/: new mechanism for SPI commands (more general than reg/buf requests)
- ep0.c (setup_request): store combined request code in "req", for
  later reuse
- include/ep0.h (ATUSB_SPI_WRITE, ATUSB_SPI_READ1, ATUSB_SPI_READ2),
  ep0.c (setup_request): new requests that translate easily into
  general SPI operations
