I think a found a minor error in Steve Sakoman's overo.h for the Gumstix COMs.  Line 172 in http://www.sakoman.com/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;f=board/overo/overo.h;h=b41b628899eebb0d98c9ea91b11cf8c5cce2648d;hb=HEAD reads:

MUX_VAL(CP(CAM_FLD),            (IDIS | PTD | DIS | M4)) /*CAM_FLD*/\

The comments at the top of the file state that the comments on each line give the final mux configuration for the pin.  Table 7-4 in spruf98v.pdf says that CONTROL_PADCONF_CAM_FLD[15:0] in mode 4 is gpio_98.  Am I missing something, or should the line read:
MUX_VAL(CP(CAM_FLD),            (IDIS | PTD | DIS | M4)) /*GPIO_98*/\
