- usb.sch (R1): changed from 68 Ohm to 180 Ohm, to decrease BOM size

and it can only help to reduce harmonics)
- atusb.sch, usb.sch, atrf.sch: bumped version to 20110214
- atusb.cmp: updated
The Makefile didn't see the FreakUSB object files at the expected place,
so it always rebuild them.
- Makefile (USB_OBJS): removed paths from object file names
- Makefile: added vpaths for the FreakUSB source file locations

object files
- include/atrf.h (atrf_set_clkm), lib/atrf.c (atrf_set_clkm): set or
disable CLKM

generic function to set CLKM without restrictions

to set CLKM

instead of code point
- atrf.c (struct atrf_dsc): added field "chip_id" to cache chip ID
- atrf.c (identify, atrf_identify): moved identification logic to new
function
- atrf.c (atrf_open, atrf_identify): cache chip ID when opening the
device and return ID from cache
- atusb.c (main), board.h (board_init), board.c (board_init): moved
clock and I/O initialization to board file
- board.h (led), board.c (led), atusb.c (main): abstracted LED setting
in function "led" instead of open-coding it
- spi.c (spi_init): set nSS to 1 before enabling the output, so that we
don't generate what looks like an empty SPI transaction
- atusb.brd: moved C14 and adjacent via 10 mil away from the transceive,
for improved solderability
- atusb.brd: moved nRST_RF via and trace by 5 mil, for better access to
the trace
- atusb.brd: reduced crystal front ground zone such that it does not
creep under XTAL2 corner (where it might meet exposed metal)
- board.h (read_irq), board.c: return status of the RF IRQ
- board.h (PIN, PIN_1, PIN_2): macros to read port pins
- ep0.c (my_setup): make ATUSB_POLL_INT return the real interrupt

ATmega32U2-based boards
- fw/ep0.c: define HW_TYPE as HW_TYPE_110131, not directly as 2

ATUSB_RF_RESET and ATUSB_REG_WRITE to indicate status stage
- Makefile (OBJS): added spi.o

it work in our context

possible, to avoid shorts with exposed contacts
