cec090f7b2 atusb.brd: more layout cleanup to improve solderability
Traces leaving a pad on the side may invite solder bridges to "false pads"
exposed at the edges of the chip, with unknown consequences.

- atusb.brd: make trace from P0.0 (IRQ_RF) leave pad at the front, not
  at the side
- atusb.brd: make trave from P0.7 (SCLK) leave pad at front, not at the
  side

6f956290c3 atusb/cam2/mkmk: double backslash to put into generated makefile

7514fa8400 atusb.brd: added via from nRST/C2CK, to allow for addition of pull-up

ad2c72fa7f atusb: firmware update for the 2010-12-16 board series
- fw/Makefile: replaced "make" with $(MAKE) (just for style)
- common/Makefile.common: Makefile settings shared within project. For now,

  in a way that doesn't need updating if a signal moves from one pin to
  another
- include/atusb/ep0.h: added hardware type 1 (2010-12-16 design)
